A reasonable police inventory search is an exception to the warrant requirement. At issue is whether an inventory is 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 the individual’s 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 the 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 has the motive only to assist and not to search for evidence, has a reasonable belief that the defendant needs help, and once the entry is made absent probable cause, that objective evidence exists 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 has 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 the parolee’s 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 when 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). When a convicted defendant is awaiting sentencing for a drug related offense and 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). A blood test not taken in compliance with the implied consent law is admissible if the taking of the sample meets 4th amendment reasonableness standards. Under Schmerber, 384 U.S. 757 (1966), the drawing of a blood sample against a person’s will is reasonable when: 1) drawn incident to an arrest; 2) there is a clear indication that the desired evidence will be found in the blood sample; and 3) exigent circumstances exist. State v. Krause, 168 Wis. 2d 578, 484 N.W.2d 347 (Ct. App. 1992). But see Missouri v. McNeely, 569 U.S. 141, 133 S. Ct. 1552, 185 L. Ed. 2d 696 (2013); Birchfield v. North Dakota, 579 U.S. 438, 136 S. Ct. 2160, 195 L. Ed. 2d 560 (2016). The question of whether the forcible extraction of a blood sample is a reasonable search by 4th amendment standards is not limited to whether the force is necessary to accomplish a legitimate police objective. Instead, whether the force used is excessive is determined by an evaluation of whether the officers’ actions are objectively reasonable in light of the facts and circumstances confronting the officers. The court judges the reasonableness of a questioned action by balancing its intrusion on the individual’s 4th amendment interests against its promotion of legitimate governmental interests and from the perspective of a reasonable officer on the scene, rather than with the 20/20 vision of hindsight. 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 when 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 when 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 when 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). 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). Discussing the six-factor analysis for use in determining the reasonableness of an investigatory stop. State v. King, 175 Wis. 2d 146, 499 N.W.2d 190 (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 when probable cause to arrest was present. State v. Koch, 175 Wis. 2d 684, 499 N.W.2d 152 (1993). Students have no reasonable privacy expectation in lockers when a school adopts a written policy retaining ownership and possessory control of the lockers. Isiah B. v. State, 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 when 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. Betterley, 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). A determination that an area is 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, 520 N.W.2d 923 (Ct. App. 1994). The plain view exception applies if the following criteria are met: 1) the officer has prior justification for being present; 2) the evidence is in plain view and its discovery inadvertent; and 3) the seized item and facts known by the officer at the time of seizure provide probable cause to believe there is a connection between a crime and the evidence. State v. Angiolo, 186 Wis. 2d 488, 520 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), and 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. DATCP, 189 Wis. 2d 255, 525 N.W.2d 758 (Ct. App. 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 when 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).
