These folks are making this persecution up to cover their backsides. Plus, just maybe, they could get enough money to buy a new car, a proper tag and some insurance!! Oh, and a new cat or dog to sacrifice.
See my Post 44 and Post 16. They had insurance. Officer Hellfire only discovered the improper tag after making the stop. The only reason for the stop was the bumper sticker. And if you want to argue that Officer Hellfire knew the tag was improper before making the stop, then you have to believed that cops are routinely driving down the road calling in tags for absolutely no reason.
Maybe they're lying, but why would they say this guy sent them a card and not show it?
