  PROBABLE CAUSE AND WARRANTS

  Probable cause meeting constitutional requirements for issuance of the search warrant of defendant's premises was not established by testimony of a police officer that a youth found in possession of amphetamines informed the officer that a shipment of marijuana was being delivered to defendant's premises, where it was established that the officer had had no previous dealings with the informant and could not personally attest to the informant's reliability; hence the search warrant was invalid. State ex rel. Furlong v. Waukesha County Court, 47 W (2d) 515, 177 NW (2d) 333.

  Probable cause for arrest without a warrant under the 4th amendment of the U.S. constitution is applicable in this state. Tests for probable cause discussed.

State, 77 W (2d) 370, 253 NW (2d) 204.

  Affidavits for search warrants need not be drafted with technical specificity nor demonstrate quantum of probable cause required in a preliminary examination; the usual inferences which reasonable men draw from evidence are permissible, and doubtful or marginal cases should be resolved by the preference to be accorded to warrants. State v. Starke, 81 W (2d) 399, 260 NW (2d) 739.

  Probable cause for arrest on charge of homicide by intoxicated use of motor vehicle justified taking blood sample without search warrant or arrest. State v. Bentley, 92 W (2d) 860, 286 NW (2d) 153 (Ct. App. 1979).

Watkinson, 161 W (2d) 750, 468 NW (2d) 763 (Ct. App. 1991), State v. Williams, 168 W (2d) 970, 485 NW(2d) 42 (1992).

  Compliance with announcement rule must be determined at time of execution: while advance request for "no-knock" authority is preferable if police at time of execution have grounds, failure to seek authorization is not fatal. State v. Kerr, 174 W (2d) 55, 496 NW (2d) 742 (Ct. App. 1993).

  The incorrect identification of a building's address in the warrant did not render the resulting search unreasonable when the search made was of the building identified by the informant which was otherwise correctly identified in the warrant. State v. Nicholson, 174 W (2d) 542, 497 NW (2d) 791 (Ct. App. 1993).

  Any item used as a basis for probable cause in a post-warrantless arrest determination must be sworn to, but lack of a sworm statement may be harmless error if the statement used had sufficient reliability and the allegations were not altered when memorialized in a sworn complaint. State v. Evans, 187 W (2d) 66, ___NW (2d) ___ (Ct. App. 1994).

  Anonymous telephone tip that specified vehicle was driven by unlicensed person did not create articulable and reasonable suspicion of illegality justifying investigatory stop of auto and driver. 68 Atty. Gen. 347.

  Police officers properly in an apartment where drugs were discovered may pat down the pockets of a stranger who walks in and may seize a large, hard object felt, in order to protect themselves. State v. Chambers, 55 W (2d) 289, 198 NW (2d) 377.

  When officers stopped a car containing 3 men meeting the description of robbery suspects within 7 minutes after the robbery and found a gun on one, they could properly search the car for other guns and money. State v. Russell, 60 W (2d) 712, 211 NW (2d) 637.

  Given a valid arrest, a search is not limited to weapons or evidence of a crime, nor need it be directed to or related to the purpose of the arrest, because one who has contraband or evidence of crime on him travels at his own risk when he is validly arrested for any reason, hence the reasonableness of a search incident thereto no longer depends on the purpose of the search in relation to the object of the arrest. State v. Mabra, 61 W (2d) 613, 213 NW (2d) 545.

  The seizure by police officers of a box of cartridges from under the edge of a couch on which defendant was resting at the time of his arrest was proper under the plain-view doctrine, since if police have a prior justification to be present in a position to see an object in plain view and its discovery is inadvertent, the object may be seized, and the use of a flashlight by one of the officers did not defeat the inadvertence requirement. Sanders v. State, 69 W (2d) 242, 230 NW (2d) 845.

  Totality of circumstances justified search for concealed weapon. Penister v. State, 74 W (2d) 94, 246 NW (2d) 115.
