But the case was concerning someone suspected of stalking, so how can the case be precedent for a non-suspect? It seems to me that this is dicta and that the only clear ruling was that the policy can use it for cases in which a complaint and underlying report of criminal activity are already occurring.
I still don’t like the fact that they can attach something to my car.
Will they be able to attach something to my clothing next?
Google “RFID”. These tags that can/are being used for “inventory purposes” on nearly ANY iten (clothes included) could be used to monitor us. The “REAL ID” Act really opened the flood gates for this crap. Cars have “black boxes” in them. Your cell phone is a homing beacon.
Perhaps a yellow "Star of David" or a Christian Cross?
You asked — Will they be able to attach something to my clothing next?

Already in the works or being done now. RFID chips are doing it and can end up tracking one particular person by their clothing, all that they wear.
