Michigan Senate bill would restrict license plate reader data retention, require warrants

Our Take

Credit to WWMT-TV for putting a camera on this one, because most Michigan drivers have no idea how many ALPR cameras are logging their movements every single day. A bill that requires warrants before cops can dig through plate reader data and puts a hard limit on how long that data sits around is exactly the kind of guardrail this technology has needed since day one. Right now in most states, Flock Safety and similar systems operate in a legal gray zone where your travel patterns get vacuumed up and stored indefinitely with zero judicial oversight.

Warrant requirements matter because they put a human being — a judge — between your license plate and a database search. Retention limits matter because indefinite storage turns a traffic camera into a permanent surveillance ledger of everywhere you've ever driven. Without both pieces, you don't have accountability, you have a backdoor for warrantless tracking dressed up as public safety tech. Michigan lawmakers taking this seriously is a signal other state legislatures should be watching closely.

This is the kind of bill that only moves forward when enough people in a state start asking questions about the cameras lining their roads.
