Radar detector or laser jammer in VA is just a defective equipment ticket, $40. They do not confiscate your equipment. In fact, if it has a serial number on it, they just write it down and hand it back to you. Otherwise, they impound it, but you get it back once you cop to the ticket.
Last time I got a reckless ticket, it was reduced to excess speed, but I had to take the on-line class (which is hard!) and hire a locally-connected attorney to make that happen.
I actually see cops running a trap at that spot from time to time (near the Dominican Retreat entrance) but I'm used to them doing it with RADAR, not LIDAR. Does the ticket say LIDAR?
Was it Fairfax County police (the station is less than a mile from there) or a Virginia Trooper?
