The criteria used as justification for warrantless searches of students by teachers discussed. Interest of L.L. v. Washington County Cir. Ct. 90 Wis. 2d 585, 280 N.W.2d 343 (Ct. App. 1979).
A warrantless entry under the emergency rule justified a subsequent entry that did not expand the scope or nature of the original entry. La Fournier v. State, 91 Wis. 2d 61, 280 N.W.2d 746 (1979).
An investigatory stop-and-frisk for the sole purpose of discovering a suspect's identity was lawful under the facts of the case. State v. Flynn, 92 Wis. 2d 427, 285 N.W.2d 710 (1979).
Furnishing police with bank records of a depositor who had victimized the bank was not an unlawful search and seizure. State v. Gilbertson, 95 Wis. 2d 102, 288 N.W.2d 877 (Ct. App. 1980).
Evidence obtained during a mistaken arrest is admissible as long as the arresting officer acted in good faith and had reasonable articulable grounds to believe that the suspect was the intended arrestee. State v. Lee, 97 Wis. 2d 679, 294 N.W.2d 547 (Ct. App. 1980).
A warrantless entry into the defendant's home was validated by the emergency doctrine where the officer reasonably believed lives were threatened. State v. Kraimer, 99 Wis. 2d 306, 298 N.W.2d 568 (1980).
The warrantless search of a fisherman's truck by state conservation wardens under statutory inspection authority was presumptively reasonable. State v. Erickson, 101 Wis. 2d 224, 303 N.W.2d 850 (Ct. App. 1981).
A detained suspect's inadvertent exposure of contraband was not an unreasonable search. State v. Goebel, 103 Wis. 2d 203, 307 N.W.2d 915 (1981).
Under Michigan v. Tyler, the warrantless search of an entire building on the morning after a localized fire was reasonable as it was the continuation of the prior night's investigation that had been interrupted by heat and nighttime circumstances. State v. Monosso, 103 Wis. 2d 368, 308 N.W.2d 891 (Ct. App. 1981).
A warrantless entry into a home was validated by the emergency doctrine where an official's reasonable actions were motivated solely by the perceived need to render immediate aid or assistance, not by the need or desire to obtain evidence. State v. Boggess, 115 Wis. 2d 443, 340 N.W.2d 516 (1983).
A warrantless noninventory search of an automobile incident to arrest was permissible under the Belton rule. State v. Fry, 131 Wis. 2d 153, 388 N.W.2d 565 (1986).
Police having probable cause to believe a vehicle contains criminal evidence may search the vehicle without a warrant or exigent circumstances. State v. Tompkins, 144 Wis. 2d 116, 423 N.W.2d 823 (1988).
Fire fighting presents exigent circumstances justifying a warrantless entry. A fire fighter may contact police to inform them of the presence of illegal possessions in plain view. A subsequent warrantless search and seizure is proper. State v. Gonzalez, 147 Wis. 2d 165, 432 N.W.2d 651 (Ct. App. 1988).
A reasonable police inventory search is an exception to the warrant requirement. At issue is whether an inventory was a pretext for an investigative search. State v. Axelson, 149 Wis. 2d 339, 441 N.W.2d 259 (Ct. App. 1989).
When effecting a lawful custodial arrest of an individual in his home, a law enforcement officer may conduct a search of closed areas within the immediate area of the arrestee even though the search imposes an infringement on the arrestee's privacy interests. State v. Murdock, 155 Wis. 2d 217, 455 N.W.2d 618 (1990).
Under the circumstances presented, an officer properly conducted an inventory search resulting in the discovery of contraband in a purse left in a police car because the search was conducted pursuant to proper department policy. State v. Weide, 155 Wis. 2d 537, 455 N.W.2d 899 (1990).
Police corroboration of innocent details of an anonymous tip may give rise to reasonable suspicion to make a stop under the totality of circumstances. A suspect's actions need not be inherently suspicious in and of themselves. State v. Richardson, 156 Wis. 2d 128, 456 N.W.2d 830 (1990).
The validity of a "Good Samaritan" stop or entry requires that the officer had the motive only to assist and not to search for evidence, had a reasonable belief that the defendant needed help, and once the entry was made absent probable cause, that objective evidence existed giving rise to the investigation of criminal behavior. State v. Dunn, 158 Wis. 2d 138, 462 N.W.2d 538 (Ct. App. 1990).
The reasonableness of a search does not come into question unless a person had a reasonable privacy expectation. There is no reasonable expectation of privacy in TDD communications made from the dispatch area of a sheriff's department. State v. Rewolinski, 159 Wis. 2d 1, 464 N.W.2d 401 (1990).
A parolee's liberty is conditional. A judicially issued warrant is not required for the seizure of an alleged parole violator in his home. State v. Pittman, 159 Wis. 2d 764, 465 N.W.2d 245 (Ct. App. 1990).
The evidentiary search of a person not named in a search warrant but present during the search of a residence reasonably suspected of being a drug house, was reasonable. State v. Jeter, 160 Wis. 2d 333, 466 N.W.2d 211 (Ct. App. 1991).
A warrantless search of an apartment for evidence of occupancy where the police reasonably believed the tenant had vacated and the occupants were not legitimately on the premises was not unreasonable. The defendant had no reasonable expectation of privacy in the apartment or in property kept there. State v. Whitrock, 161 Wis. 2d 960, 468 N.W.2d 696 (1991).
Blood may be drawn in a search incident to an arrest if police have reasonable suspicion that blood contains evidence of a crime. State v. Seibel, 163 Wis. 2d 164, 471 N.W.2d 226 (1991).
Where it is asserted that a search was incident to an arrest, an objective test that assesses the totality of circumstances is applied to determine if an arrest occurred. Where no arrest has occurred there can be no full warrantless search. The prior subjective test is abrogated. State v. Swanson, 164 Wis. 2d 437, 475 N.W.2d 148 (1991).
When a convicted defendant is awaiting sentencing for a drug related offense where probation is a sentencing option, the judge may order, without a warrant, probable cause or individualized suspicion, that the defendant submit to urinalysis to determine if drugs are present. State v. Guzman, 166 Wis. 2d 577, 480 N.W.2d 446 (1992).
Drawing of blood sample without consent is reasonable when, 1) it is drawn incident to an arrest, 2) there is a clear indication that the desired evidence will be found and 3) exigent circumstances exist. Rapid dissipation of blood alcohol is an exigent circumstance. Force allowable in obtaining a sample discussed. State v. Krause, 168 Wis. 2d 578, 484 N.W.2d 347 (Ct. App. 1992).
The exception allowing the warrantless search of automobiles is not extended to a camper trailer unhitched from a towing vehicle. State v. Durbin, 170 Wis. 2d 475, 489 N.W.2d 655 (Ct. App. 1992).
A warrantless search of a commercial premises without the owner's consent where a licensing ordinance provided that the licensed premises "shall be open to inspection at any time" was illegal. State v. Schwegler, 170 Wis. 2d 487, 490 N.W.2d 292 (Ct. App. 1992).
The frisk of a person not named in a search warrant during the execution of the warrant was reasonable where the occupants of the residence were very likely to be involved in drug trafficking. Drugs felt in a pocket during the frisk were lawfully seized where the officer had probable cause to believe there was a connection between what was felt and criminal activity. State v. Guy, 172 Wis. 2d 86, 492 N.W.2d 311 (1992).
Dissipation of alcohol in the bloodstream constitutes a sufficient exigency to justify a warrantless blood draw when made at an officer's direction following an arrest for OWI. State v. Bohling, 173 Wis. 2d 529, 494 N.W.2d 399 (1993).
A warrantless protective sweep of a residence incident to an arrest requires the police to have a reasonable suspicion based on articulable facts that the residence harbors an individual posing a danger to the officers. State v. Kruse, 175 Wis. 2d 89, 499 N.W.2d 185 (Ct. App. 1993).
The six factor analysis for use in making determination of reasonableness of investigatory stop is discussed. State v. King, 175 Wis. 2d 146, N.W.2d (Ct. App. 1993).
The rule that a judicial determination of probable cause to support a warrantless arrest must be made within 48 hours applies to Wisconsin. The failure to comply did not require suppression of evidence not obtained because of the delay where probable cause to arrest was present. State v. Koch, 175 Wis. 2d 684, 499 N.W.2d 153 (1993).
Where a school adopts a written policy retaining ownership and possessory control of lockers, students have no reasonable privacy expectation in those lockers. Interest of Isiah B. 176 Wis. 2d 639, 500 N.W.2d 637 (1993).
An officer's step onto the threshold of the defendant's home constituted an entry subject to constitutional protection. State v. Johnson, 177 Wis. 2d 224, 501 N.W.2d 876 (Ct. App. 1993).
A defendant under lawful arrest has a diminished privacy interest in personal property inventoried by jail authorities and a warrantless search of the property where there is probable cause to believe it contains evidence is valid. State v. Jones, 181 Wis. 2d 194, 510 N.W.2d 784 (Ct. App. 1993). See also State v. Betterly, 183 Wis. 2d 165, 515 N.W.2d 911 (Ct. App. 1994).
A warrantless entry by uniformed officers to make arrests after undercover agents gained permissive entrance to the premises was justified under the consent exception and no exigent circumstances were required. State v. Johnston, 184 Wis. 2d 794, 518 N.W.2d 759 (1994).
A non-parolee living with a parolee has a legitimate expectation of privacy in shared living quarters, but a warrantless search authorized as a condition of parole can reasonably extend to all areas in which the parolee and non-parolee enjoy common authority. Evidence found in such a search may be used against the non-parolee. State v. West, 185 Wis. 2d 68, 517 N.W.2d 482 (1994).
The failure to conduct a probable cause hearing within 48 hours of arrest is not a jurisdictional defect and not grounds for dismissal with prejudice or voiding of a subsequent conviction unless the delay prejudiced the defendant;'s right to present a defense. State v. Golden, 185 Wis. 2d 763, 519 N.W.2d 659 (Ct. App. 1994).
Evidence obtained in a consensual search of the defendant's car where the consent was given during an illegal search was admissible as the evidence was not "come at" by information learned in the interrogation. State v. Goetsch, 186 Wis. 2d 1, 519 N.W.2d 634 (Ct. App. 1994).
A determination that an area was within a defendant's immediate control at the time of arrest does not give police authority to generally search the premises. Only a limited search is justified. State v. Angiolo, 186 Wis. 2d 488, N.W.2d 923 (Ct. App. 1994).
The plain view exception applies if the following criteria are met: 1) the officer must have prior justification for being present, 2) the evidence must be in plain view and its discovery inadvertent and 3) the seized item and facts known by the officer at the time of seizure must provide probable cause to believe there is a connection between a crime and the evidence. State v. Angiolo, 186 Wis. 2d 488, N.W.2d 923 (Ct. App. 1994).
Unlike private homes, warrantless inspections of commercial premises are not necessarily unreasonable. A warrantless inspection of a dairy farm under authority of ss. 93.08, 93.15 (2), 97.12 (1) and related administrative rules made without prior notice and without the owner being present was not unconstitutional. Because the administrative rules govern operations, equipment and processes not typically conducted in residential areas, the rules and statutes sufficiently preclude making warrantless searches of residences. Lundeen v. Dept. of Agriculture, 189 Wis. 2d 255, 525 N.W.2d 758 (1994).
An arrest warrant was not legal authority to enter and search the home of a third-party based on an officer's simple belief that the subject of the warrant might be there. The mere fact that the subject could leave was not an exigent circumstance justifying the warrantless search where the warrant was a pick-up warrant for failure to pay a traffic fine. State v. Kiper, 193 Wis. 2d 69, 532 N.W.2d 698 (1995).
Suppression of evidence is not required when a law enforcement officer obtains evidence outside his or her jurisdiction. Any jurisdictional transgression violates the appropriate jurisdiction's authority not the defendant's rights. State v. Mieritz, 193 Wis. 2d 571, 534 N.W.2d 632 (Ct. App. 1995).
A warrantless search of a vehicle was constitutional where the defendant fled the vehicle to avoid arrest. The defendant did not have a reasonable expectation of privacy in the vehicle. State v. Roberts, 196 Wis. 2d 445, 538 N.W.2d 825 (Ct. App. 1995).
Whether a pat-down search is reasonable requires the officer to have a reasonable suspicion that a suspect is armed. Finding reasonableness requires looking at the totality of the circumstances. The officer's perception of the area as a high-crime area, the time of day and the suspect's nervousness are all factors that may be considered. State v. Morgan, 197 Wis. 2d 200, 539 N.W.2d 887 (1995).
Whether persons have "common authority" to consent to a search of a premises depends, not on property rights, but on the relationship between the consenting party and the premises. Co-residents have "common authority" to consent to a search, but relatives of residents and property owners do not. Consent of one who possesses common authority is binding against an absent resident, but is not binding against a nonconsenting party who is present. State v. Kieffer, 207 Wis. 2d 464, 558 N.W.2d 664 (Ct. App. 1996); Affirmed 217 Wis. 2d 531, 577 N.W.2d 352 (1998).
A probation officer may conduct a warrantless search. That the underlying conviction is subsequently overturned does not retroactively invalidate the search. State v. Angiolo, 207 Wis. 2d 559, 558 N.W.2d 701 (Ct. App. 1996).
An initial traffic stop is not unlawfully extended by asking the defendant if he had drugs or weapons and requesting permission to search. Where there is justification for the initial stop, it is the extension of the stop beyond the point reasonably justified by the stop and not the type of questions asked that render a stop unconstitutional. State v. Gaulrapp, 207 Wis. 2d 598, 558 N.W.2d 696 (Ct. App. 1996).
An officer has the right to remain at an arrested person's elbow at all times. When an officer accompanied a juvenile in his custody into the juvenile's house, leaving the juvenile's "elbow" to enter a bedroom where incriminating evidence was found, monitoring of the juvenile stopped and an unconstitutional search occurred. State v. Dull, 211 Wis. 2d 651, 565 N.W.2d 575 (Ct. App. 1997).
A threat to the safety of the suspect or others is an exigent circumstance justifying the warrantless entry of a residence. The mere presence of firearms does not create exigent circumstances. Where conducting an unannounced warrantless entry creates the potential danger, that conduct cannot justify the warrantless entry. State v. Kiekhefer, 212 Wis. 2d 460, 569 N.W.2d 316 (Ct. App. 1997).
The likelihood that evidence will be destroyed is an exigent circumstance justifying the warrantless entry of a residence. The mere presence of contraband does not create exigent circumstances. State v. Kiekhefer, 212 Wis. 2d 460, 569 N.W.2d 316 (Ct. App. 1997).
Detaining a person at his home and transporting him about one mile to the scene of an accident in which he was involved was an investigative stop and not an arrest, moved the person within the vicinity of the the stop within the meaning of s. 968.24 and was a reasonable part of an ongoing accident investigation. State v. Quartana, 213 Wis. 2d 440, 570 N.W.2d 618 (Ct. App. 1997).
The warrantless search of the defendant's purse when it was being returned to her while still in custody was authorized where the search would have been authorized at the time of the arrest and where the return of the purse could have given the defendant access to a weapon or evidence. State v. Wade, 215 Wis. 2d 678, 573 N.W.2d 228 (Ct. App. 1998).
Where a third-party lacks actual common authority to consent to a search of a defendant's residence, the police may rely on the third-party's apparent authority, if that reliance is reasonable. There is no presumption of common authority to consent to a search and the police must make sufficient inquiry to establish apparent authority. State v. Kieffer, 217 Wis. 2d 531, 577 N.W.2d 352 (1998).
A warrantless entry may be justified where the police engage in a bona fide community caretaker activity, although the ultimate test is reasonableness. The relevant considerations are the degree of public interest and exigency of the situation, the circumstances surrounding the search, whether an automobile is involved and whether there are alternatives to entry. State v. Paterson, 220 Wis. 2d 526, 583 N.W.2d 190 (Ct. App. 1998).
Reasonable suspicion required in a Terry investigative search is a common sense test of what under the circumstances a reasonable police officer would reasonably suspect in light of his or her experience. Police in an area known for drug dealing were justified to stop a driver when at nearly the same time they observed a woman approach then turn from the driver's parked car when she seemed to notice the police and the driver immediately exited the parking lot he was in. State v. Amos, 220 Wis. 2d 793, 584 N.W.2d 170 (Ct. App. 1998).
There is an expectation of privacy in commercial property that is applicable to administrative inspections. Because administrative inspections are not supported by probable cause, they will not be reasonable if, instead of being conducted to enforce a regulatory scheme, they are conducted as a pretext to obtain evidence of criminal activity. State v. Mendoza, 220 Wis. 2d 803, 584 N.W.2d 174 (Ct. App. 1998). Reversed on other grounds. State v. Mendoza, 227 Wis. 2d 838, 596 N.W.2d 736 (Ct. App. 1998).
There is no reasonable expectation of privacy in a hospital emergency or operating room. An officer who was present, with the consent of hospital staff, in an operating room during an operation and collected, as evidence, cocaine removed from an unconscious defendant's intestine did not conduct a search and did not make an unreasonable search. State v. Thompson, 222 Wis. 2d 179, 585 N.W.2d 905 (Ct. App. 1998).
A warrant authorizing the search of a particularly described premises may permit the search of vehicles owned or controlled by the owner of, and found on, the premises. State v. O'Brien, 223 Wis. 2d 303, 588 N.W.2d 8 (1999).
The "emergency doctrine" justifies a warrantless search when an officer is actually motivated by a perceived need to render aid and a reasonable person under the circumstances would have thought an emergency existed. State v. Richter, 224 Wis. 2d 814, 592 N.W.2d 310 (Ct. App. 1999).
Reasonable suspicion justifying an investigative stop may be based on an anonymous tip that does not predict future behavior. The key concern is the tipster's veracity. Officers' corroboration of readily observable information supports a finding that because the tipster was correct about innocent activities, he or she is probably correct about the ultimate fact of criminal activity. State v. Williams, 225 Wis. 2d 159, 591 N.W.2d 823 (1999).
A traffic stop must be based on probable cause, not reasonable suspicion. If the facts support a violation only under a legal misinterpretation, no violation has occurred, and by definition there can be no probable cause that a violation has occurred. State v. Longcore, 226 Wis. 2d 1, 594 N.W.2d 412 (Ct. App. 1999).
Being in a high crime area, making brief contact with a car, and hanging around a neighborhood each standing alone would not create reasonable suspicion justifying a Terry stop. When these events occurred in sequence and were considered with the officers training and experience, the reputation of the neighborhood, and the time of day, there was enough to create reasonable suspicion. State v. Allen, 226 Wis. 2d 66, 593 N.W.2d 504 (Ct. App. 1999).
Once a justifiable stop is made, the scope of the officer's inquiry may be broadened beyond the original purpose for which the person was stopped if additional particularized and objective, suspicious factors come to the officer's attention. A picture of a mushroom on the defendant's wallet, his appearance of nervousness, and the lateness of the hour were insufficient factors to extend a stop. State v. Betow, 226 Wis. 2d 90, 593 N.W.2d 499 (Ct. App. 1999). See also State v. Gammons, 2001 WI App 36, 241 Wis. 2d 296, 625 N.W.2d 623.
The owner of a commercial property has a reasonable expectation of privacy in those areas immediately surrounding the property only if affirmative steps have been taken to exclude the public. State v. Yakes, 226 Wis. 2d 425, 595 N.W.2d 108 (Ct. App. 1999).
A home's backyard and back door threshold were within the home's curtilage; an officer's warrantless entry was unlawful and evidence seized as a result of the entry was subject to suppression. State v. Wilson, 229 Wis. 2d 256, 600 N.W.2d 14 (Ct. App. 1999).
When the 2 other occupants of a vehicle had already been searched without any drugs being found, a search of the 3rd occupant based solely on the odor of marijuana was made with probable cause and was reasonable. State v. Mata, 230 Wis. 2d 567, 602 N.W.2d 158 (Ct. App. 1999).
A probation officer may search a probationer's residence without a warrant if the officer has reasonable grounds to believe the terms of probation are being violated, but the officer may not conduct a warrantless search as a subterfuge to further a criminal investigation to help the police evade the usual warrant and probable cause requirements. State v. Hajicek, 230 Wis. 2d 697, 602 N.W.2d 93 (Ct. App. 1999).
The risk that evidence will be destroyed is an exigent circumstance that may justify a warrantless search. When suspects are aware of the presence of the police, that risk increases. The seriousness of the offense as determined by the overall penalty structure for all potentially chargeable offenses also affects whether exigent circumstances justify a warrantless search. State v. Hughes, 2000 WI 24, 233 Wis. 2d 280, 607 N.W.2d 621.
Police officers do not need to choose between completing a protective frisk and handcuffing a suspect in a field investigation. They may do both. State v. McGill, 2000 WI 38, 234 Wis. 2d 560, 609 N.W.2d 795.
A frisk of a motor vehicle passenger that occurred 25 minutes after the initial stop that was a precautionary measure, not based on the conduct or attributes of the person frisked, was unreasonable. State v. Mohr, 2000 WI App 111, 235 Wis. 2d 220, 613 N.W.2d 186.
When a vehicle passenger has been seized pursuant to a lawful traffic stop, the seizure does not become unreasonable because an officer asks the passenger for identification. The passenger is free to refuse to answer, and refusal will not justify prosecution nor give rise to reasonable suspicion of wrongdoing. However, if the passenger chooses to answer falsely, the passenger can be charged with obstruction. State v. Griffith, 2000 WI 72, 236 Wis. 2d 48, 613 N.W.2d 72.
"Hot pursuit", defined as immediate or continuous pursuit of a suspect from a crime scene is an exigent circumstance justifying a warrantless search. An officer is not required to personally observe the crime or fleeing suspect. State v. Richter, 2000 WI 58, 235 Wis. 2d 524, 612 N.W.2d 29.
The property of a passenger in a motor vehicle may be searched when the police have validly arrested the driver but do not have a reasonable basis to detain or probable cause to arrest the passenger. State v. Pallone, 2000 WI 77, 236 Wis. 2d 162, 613 N.W.2d 568.
The search of a crawl space in a ceiling, which was located in an area where police had heard much activity, was large enough to hide a person, and was secured by screws that had to be removed with a screwdriver, was a reasonable "protective sweep" to search for persons who would pose a threat to the police as they executed an arrest warrant for a murder suspect. State v. Blanco, 2000 WI App 119, 237 Wis. 2d 395, 614 N.W.2d 512.
A police officer performing a Terry stop and requesting identification could perform a limited search for identifying papers when the information received by the officer was not confirmed by police records, the intrusion on the suspect was minimal, the officer observed that the suspect's pockets were bulging, and the officer had experience with persons who claimed to have no identification when in fact they did. State v. Black, 2000 WI App 175, 238 Wis. 2d 203, 617 N.W.2d 210.
The Paterson community caretaker exception justified a warrantless entry during an emergency detention of a mentally ill person who was threatening suicide. A protective sweep of the premises while acting as a community caretaker was reasonable. State v. Horngren, 2000 WI App 177, 238 Wis. 2d 347, 617 N.W.2d 508.
A warrantless blood draw is permissible when: 1) the blood is taken to obtain evidence of intoxication from a person lawfully arrested; 2) there is a clear indication that evidence of intoxication will be produced; 3) the method used is reasonable and performed in a reasonable manner; and 4) the arrestee presents no reasonable objection. State v. Thorstad, 2000 WI App 199, 238 Wis. 2d 666, 618 N.W.2d 240.
That a driver stopped at a stop sign for a few seconds longer than normal, that it was late in the evening, and that there was little traffic did not give rise to a reasonable suspicion that the driver was committing an unlawful act. State v. Fields, 2000 WI App 218, 239 Wis. 2d 38, 619 N.W.2d 279.
A warrantless entry need not be subjectively motivated solely by a perceived need to render aid and assistance in order for the "emergency doctrine" to apply. A dual motivation of investigating a potential crime and rendering aid and assistance may be present. State v. Rome, 2000 WI App 243, 239 Wis. 2d 491, 620 N.W.2d 225.
Whether a search is a probation search, which may be conducted without a warrant, or a police search, which may not, is a question of constitutional fact to be reviewed in a 2-step review of historical and constitutional fact. A determination of reasonableness of the search must also be made. A search is reasonable if the probation officer has reasonable grounds to believe that the probationer has contraband. Cooperation with police officers does not change a probation search into a police search. State v. Hajicek, 2001 WI 3, 240 Wis. 2d 349, 620 N.W.2d 781.
In light of the reduced expectation of privacy that applies to property in an automobile, the search of a vehicle passenger's jacket based upon the driver's consent to the search of the vehicle was reasonable. State v. Matejka, 2001 WI 5, 241 Wis. 2d 52, 621 N.W.2d 891.
Before the government may invade the sanctity of the home, it must demonstrate exigent circumstances that overcome the presumption of unreasonableness that attaches to all warrantless home entries. Reluctance to find an exigency is especially appropriate when the underlying offense for which there is probable cause to arrest is relatively minor. State v. Kryzaniak, 2001 WI App 44, 241 Wis. 2d 358, 624 N.W.2d 389.
Under Florida v. J.L, an anonymous tip giving rise to reasonable suspicion must bear indicia of reliability. That the tipster's anonymity is placed at risk indicates the the informant is genuinely concerned and not a fallacious prankster. Corroborated aspects of the tip also lend credibility; the corroborated actions of the suspect need be inherently criminal in and of themselves. State v. Williams, 2001 WI 21, 241 Wis. 2d 631, 623 N.W.2d 106.
An anonymous tip regarding erratic driving from another driver celling from a cell phone contained sufficient indicia of reliability to justify an investigative stop when the informant was exposed to possible identification, and therefore possible arrest if the tip proved false; the tip reported contemporaneous and verifiable observations regarding the driving, location, and vehicle; and the officer verified many of the details in the tip. That the tip reasonably suggested intoxicated driving created an exigency strongly in favor of immediate police investigation without the necessity that the officer personally observe erratic driving, State v. Rutzinski, 2001 WI 22, 241 Wis. 2d 729, 623 N.W.2d 516.
The state constitution does not provide greater protection under the automobile exception for warrantless searches than the 4th amendment. The warrantless search of a vehicle is allowed when there is probable cause to search the vehicle and the vehicle is mobile. The exception apples to vehicles that are not in public places. There is no requirement that obtaining a warrant be impracticable. State v. Marquardt, 2001 WI App 219, 247 Wis. 2d 765, 635 N.W.2d 188.
Whether exigent circumstances existed justifying a warrantless entry to prevent destruction of evidence after the defendant saw, and retreated from, a plain-clothes officer was not a question of whether the defendant knew that the detective was a police officer, but whether it was reasonable for the officer to believe that he had been identified and that the suspect would destroy evidence as a consequence. State v. Garrett, 2001 WI App 240, 248 Wis. 2d 61, 635 N.W.2d 615.
