A Court Is Now Asking Who Can Watch Your Car. The Answer Should Worry You

A lawsuit in Waukesha County, Wisconsin, asks a judge to answer a question most drivers have never been asked: can police search a database that records where your car has been without first getting a warrant? The plaintiffs also argue that the answer to "who can watch your car" reaches well beyond your local police department. No court has ruled, but a court has now been asked.

What is happening

On Thursday, September 10, 2026, the Wisconsin Institute for Law & Liberty (WILL), which Urban Milwaukee describes as a conservative law firm, sued Waukesha County and 11 municipalities in Waukesha County Circuit Court. The municipalities include Muskego, Oconomowoc, New Berlin, Mukwonago, Waukesha and Elm Grove. WILL represents NoCams Muskego, Citizens Defending Liberty and an Oconomowoc homeowner, according to TMJ4.

The claim is that police searches of the Flock license plate camera database without a warrant violate the Fourth Amendment. WPR reports that the complaint says the municipalities "granted police officers permission to search a surveillance network" that tracks the plaintiffs' physical movements, and that they allow searches without obtaining a warrant or requiring probable cause. WILL attorney Dan Lennington said WILL is "not asking that the cameras be taken down" but wants "the constitutional standard be applied." The relief sought is a court declaration that a warrant is required to search the database. TMJ4 reports that no hearing dates have been set.

Who can watch your car, according to the plaintiffs

WILL estimates about 120 Flock cameras operate in Waukesha County. Fox6 reports they are run by municipalities and by private businesses, including Home Depot, Lowe's and hospitals. WILL alleges cameras sit "in people's backyards, outside of churches and even outside of polling places." Lennington says the system lets users "look back 30 days and create a vehicle history map."

The sharper allegation is about access. CBS58 reports WILL's position that the database is searchable by nearly anyone with an account and that no Wisconsin agency requires probable cause or a warrant before a search. Coverage of the filing cites these numbers. Urban Milwaukee reports Muskego police ran more than 300 searches in one month, while other agencies ran more than 900,000 searches using Muskego's cameras. WTMJ reports the lawsuit highlights Elm Grove, where local officers ran roughly 250 searches of the village's six cameras from June through August 2026, while outside agencies, mostly from other states, ran roughly 3 million. The coverage we reviewed does not say any outside search was improper; WILL's argument is that no warrant standard exists.

What is getting less attention

Misuse by insiders is documented elsewhere in Wisconsin. Former Milwaukee police officer Josue Ayala pleaded guilty to misdemeanor attempted misconduct in public office after, Fox6 reported, he ran 179 unauthorized Flock searches for personal reasons, each logged with the justification "investigation." Fox6 reported he was sentenced July 15, 2026, to one year of probation and a $500 fine. That case is separate from the suit, but TMJ4 reported that the push to defund Flock in Oconomowoc gained momentum after criminal charges against two former Milwaukee police officers accused of misusing Flock's database.

The legal backdrop is also moving. In June 2026 the Supreme Court decided Chatrie v. United States, 6-3, holding that a geofence warrant for stored cellphone location history is a Fourth Amendment search, according to the National Civil Liberties Alliance. WTMJ reports WILL cites a recent Supreme Court decision on Google location data in its complaint.

And local governments are already pulling back. Oconomowoc's council voted 5-2 on September 15 to cancel its Flock contract, with a year left on an $18,000 deal. Waukesha's council voted not to fund the program beyond 2026, according to Fox6. In Milwaukee County, a committee unanimously approved removing Flock equipment from 11 parks, according to Hoodline.

The other side

Flock cameras have defenders, and the suit does not dispute that. Homeowner Jake Fell told Fox6 the cameras helped reduce crime in his area. Lennington himself told TMJ4 the cameras are "a great tool that works" but need "proper guardrails." Oconomowoc residents were divided, TMJ4 reported. Waukesha County and New Berlin declined comment on pending litigation. We found no statement from Flock Safety in the coverage we reviewed.

Our Take

This section is opinion.

We oppose a surveillance state, and we do not think a tool that logs the movements of ordinary drivers should be searchable by anyone who holds an account. The plaintiffs' allegation, that agencies far from Wisconsin can search the same database as the local police chief, is the kind of detail that should trouble anyone who believes government should stay out of people's business. Whether it is legally a Fourth Amendment search is for the court. In our view, a warrant requirement is a modest ask: WILL says it is not demanding that the cameras come down.

We also think the most important development is not in the courtroom. Elected councils in Oconomowoc, Waukesha and elsewhere are deciding, in public, to end or defund their camera programs. That is states and localities governing themselves, which is how it should work. If your town runs these cameras, ask the council who can search them, how often, and under what written policy.

Fair-minded people can weigh crime-fighting benefits differently. Convenience is not a constitutional standard, and the burden belongs on government to justify watching people who have done nothing wrong.
