This happened today, made me laugh a little.
Cop was on the left side of the highway (4 lanes each direction) next to the jerseywall picking off cars with his Laser gun (looked like the Stalker unit). The unmarked car was parked facing same direction as traffic and he was standing next to his car with the driver door open pointing the lidar gun towards the oncoming traffic. The funny thing was I slowed down long before I ever saw him because the retard had his ka radar on. X50 picked up the Ka from way back. Now this is somthing you would never see in Maryland or any other state for that matter. I'm glad the cops here assume no one has a radar detector just because they are illegal. And it's probably true that it is rare for a car to have a radar detector in Virginia, but what LEO would leave the Ka on if you are using laser?
