My question involves police conduct in the State of: Illinois
So an aquentence of mine was parked in front of my house, completely within legal rights. It was on the correct side of the road, close enough to the bumper and it was for a small amount of time during the day. Anyway, a cop scanned his plates and proceeded to go on for the day. He was off the clock, and had no cause to run the plates whatsoever. And then recently the same cop scanned his plates again at my house, although this time the car was parked in the driveway. Is this legal ? And once again, the cop was off the clock but proceeded to scan in the plates without probable cause.
