A cop friend of my parents just moved up to traffic officer. He told my parents today that he was shooting laser and was hidden and never could get a reading. So after the vehicle passed him he hit him in the rear and stopped him for speeding. He walked up to the guy and he said you have a laser jammer don't you. The subject said yes. Cop said well that doesn't do you any good for the rear does it? Subject nope. End of story he got a ticket for speeding.
So, I wonder who it was and if they are on this forum but most likely not.
