On Point: G. Reasonable suspicion

State v. Alberta R. Rose, 2013AP2783-CR, District 2, 6/4/14 (1-judge; ineligible for publication); case activity

A police officer’s observations of a car “smoothly swerving three or four times” in its lane of travel over several blocks and then “appear[ing] to strike the center line” (¶2) provided reasonable suspicion to perform a valid investigatory stop of the car, even though an enhanced version of the squad car video showed the car didn’t hit the center line.

State v. Joshua D. Winberg, 2013AP2661-CR, District 3, 5/28/14 (1-judge; ineligible for publication); case activity

The driver of a car stopped based on officer’s knowledge that the car owner’s license was revoked was not unlawfully seized because, even thought it was immediately apparent the car owner was not driving, the police also immediately observed additional suspicious information that justified the continued detention of the driver.

New Berlin v. John Francis Downey, 2013AP 2352-FT, District 2, 5/14/14 (1-judge; ineligible for publication); case activity

An on-duty police officer had authority to stop Downey outside his jurisdiction because he was acting in response to an “emergency situation,” § 175.40(6)(a), and because he was in fresh pursuit of a law violator, § 175.40(2).

State v. Andrew K. Wenz, 2013AP2576-CR, District 1, 5/13/14 (1-judge; ineligible for publication); case activity

Police had reasonable suspicion to stop his car because the content of a tip from a known, reliable informant allowed police to ascertain whether they were stopping the correct vehicle.

State v. Gumersinda M. Gonzalez, 2013AP2585-CR, District 4, 5/8/14 (1-judge; ineligible for publication); case activity

The officer lacked reasonable suspicion to extend the duration of a traffic stop by asking a driver to perform field sobriety tests, so evidence of THC possession obtained during the stop must be suppressed.

State v. Dean M. Blatterman, 2013AP2107-CR, District 4, 4/24/14 (one-judge; ineligible for publication), petition for review granted 9/24/14, reversed, 2015 WI 46; case activity

You don’t see this very often.  The court of appeals just reversed a circuit court decision denying a motion to suppress evidence of intoxication.  The police performed field sobriety and blood tests after moving the suspect out of the general vicinity of the stop.  This converted the stop into an arrest for which there was no probable cause.

Question presented:

Whether a police officer’s mistake of law can provide the individualized suspicion that the Fourth Amendment requires to justify a traffic stop.

Navarette v. California, USSC No. 12-9490, 4/22/14, affirming People v. Navarette, No. A132343, 2012 WL 4842651 (Cal. Ct. App. Oct. 12, 2013) (unpublished); Scotusblog page (includes links to the briefs and commentary)

Validating the rationale employed by the Wisconsin Supreme Court in State v. Rutzinski, 2001 WI 22, 241 Wis. 2d 729, 623 N.W.2d 516, the U.S. Supreme Court upholds the stop of a vehicle based on a 911 caller’s report that the vehicle ran her off the road, even though the police officer who located and then followed the vehicle observed no improper or erratic driving.

State v. Matthew M. Moskopf, 2013AP771-CR, District 2, 4/2/14; court of appeals decision (one judge; ineligible for publication); case activity

The police had collective knowledge of specific, articulable facts supporting a reasonable suspicion to stop Moskopf’s vehicle where two 911 calls to the police department dispatcher–one from a bartender, another from an off-duty cop–reported that a man had been trying to get back into a bar he had been kicked out of,

State v. Jesse A. Van Camp, 2013AP2059-CR, District 3, 3/25/14; court of appeals decision (1-judge; ineligible for publication); case activity

Although an “[a]dmittedly … close case” (¶15), police had reasonable suspicion to stop Van Camp under all the circumstances, including his “somewhat evasive” driving behavior, even though they observed no specific criminal activity, applying State v. Anderson, 155 Wis. 2d 77, 84,
