ALPR’s have been proven constitutional because you have no “reasonable right to privacy” in a public place. US courts already hashed this out in the 90s and state that being tracked in public is not a 4th amendment violation- which is 100% total bullshit, but the police state isn’t going to take power away from itself. Despite these systems now going above and beyond traditional ALPR systems- police pigs will hide behind the same rulings.
