No Warrant Required for GPS Tracking
As the law currently stands, the court said police can mount GPS on cars to track people without violating their constitutional rights — even if the drivers aren’t suspects.
Officers do not need to get warrants beforehand because GPS tracking does not involve a search or a seizure, Judge Paul Lundsten wrote for the unanimous three-judge panel based in Madison.
That means “police are seemingly free to secretly track anyone’s public movements with a GPS device,” he wrote.
The court wants the legislature to fix it:
However, the District 4 Court of Appeals said it was “more than a little troubled” by that conclusion and asked Wisconsin lawmakers to regulate GPS use to protect against abuse by police and private individuals.
I think the odds of that happening are approximately zero.
