Today was the first time that I witnessed a LEO (Howard County P.O) using the side mirror while shooting laser. The LEO was parked under the Route 103 overpass on Route 100 in Columbia, shooting his Pro Laser 3 and radioing the "chase car" parked along the shoulder just north of his location (before the I95 exit ramp).
Very odd that the Howard county force is using lidar again. Usually, the Howard county LEOs use K band and Ka band radar, instead of lidar. There was a ban on lidar use after one of the officers was struck and killed by a motorist in a speed trap a few years ago.
Looks like some LEOs have learned a new trick in speed enforcement; maybe they saw the videos of the motorcycle LEOs doing this trick here!
