Being Stopped by Police in Wisconsin
Police searched me or my car — here's what Wisconsin law says and what to do next.
Statute: Wis. Const. Art. I, section 11 (unreasonable searches and seizures); Wis. Stat. section 893.82 (tort claims — 120 days notice)
Deadline: 120 days
Penalty: Wisconsin requires 120-day notice before filing tort claims against the state or its officers. Constitutional protections parallel the Fourth Amendment
What is being stopped by police?
The 4th Amendment protects you from unreasonable searches and seizures. In most cases, police need a warrant signed by a judge before they can search your home, car, phone, or belongings.
There are exceptions — police can search without a warrant if you give consent, if evidence is in plain view, or in certain emergency situations. But the default rule is: no warrant, no search.
What to Do If Police Want to Search You
Step 1: Say clearly: "I do not consent to any searches." Say it calmly and repeat it if needed. This preserves your rights even if police search anyway.
Step 2: Ask: "Do you have a warrant?" If police say yes, ask to see it. A valid warrant must specify the place to be searched and the items to be seized.
Step 3: Do not physically block or resist a search, even if you believe it's illegal. Your remedy is in court, not on the scene.
Step 4: Document everything afterward. Write down what happened, what was searched, what was taken, and the names/badge numbers of officers involved.
Step 5: If evidence was obtained through an illegal search, your attorney can file a motion to suppress it (the "exclusionary rule" from Mapp v. Ohio, 1961).
How Wisconsin differs from federal law
Wisconsin's search and seizure protections come from both the Wisconsin Constitution and the Fourth Amendment:
- The Wisconsin Constitution, Art. I, § 11 protects against unreasonable searches and seizures
- Wisconsin courts generally follow federal Fourth Amendment jurisprudence
- WI requires warrants for most searches with standard exceptions (consent, exigent circumstances, plain view, search incident to arrest, automobile exception)
- Wisconsin has specific provisions for blood draws in OWI (Operating While Intoxicated) cases following Missouri v. McNeely
- Wisconsin follows the exclusionary rule for illegally obtained evidence
- Wisconsin does not allow sobriety checkpoints — the WI Supreme Court has not authorized them

What you should NOT do
Don't consent. Police may ask "mind if I take a look?" or "you don't have anything illegal, right?" These are requests for consent. You can say no.
Don't leave your door open. If police knock on your door, you can speak through the door or step outside and close it behind you. An open door can give police a "plain view" argument.
Don't unlock your phone. Police cannot force you to unlock your phone with a passcode (5th Amendment). Biometric locks (fingerprint, face) have less protection — consider disabling them during an encounter.
Don't destroy evidence. If police are approaching, do not throw away or destroy anything. That creates new charges and implies guilt.
