I've seen quite a few officers in my area with poorly mounted radar guns.
I've seen K55's pointing into the ground off the dash, I've seen other guns off axis and not even pointing up the road. These mounts have nothing to do with moving the radar for specific traps, this is just how there guns are in the cruiser. I've also see K55's on their sides while being used.
This must mess up the reading of the radar gun when used for speed enforcement, doesn't it?
