See the fact is, it's not unconstitutional to follow a suspect for 28 days without a warrant.
But the fact they touched private property to place that GPS tracker on the vehicle itself.
This new fact might prevent cops from being able to track suspects via Cell phone GPS, too.
Which would be a major setback for searching the missing or suspecting criminals.
As a law abiden citizen, I personal do approve GPS tracking by law enforcement, but on the other hand it's another piece of freedom we could all lose.
But, I think we lost that fight with cams everywhere, anyways, which should also be unconstitutional that police have access to any privately owned cam (such as 7/11 stores, buisness bulidings, etc) that tape outside of their businesses.
