That doesn’t make it right.And people like you that advocate that it’s okay to do so is why our freedoms are diminishing more and more every day. Running a plate is no different than a cop stopping a guy walking down the sidewalk minding his own business and demanding his ID just because he looks funny.
Just running a plate doesn’t effect a driver in any way, you never even know it happened unless they find something wrong.
You aren’t being stopped, searched, or detained in any way by a cop running your plate.
