Radar guns

[John S. Lagnese]

On my way home from work in Methuen, MA I often see the stae police using a 
hand held unit. This is by Exit 53 on 495 North. This is an instant on unit. 
When I am closer to home, in ME, there are occasional yahoos, er, stae 
troopers who do the same thing. They have an extremely annoying to downright 
dangerous trick. They go into a pose, simulating shooting at you with the 
radar gun. I am annoyed, but someone could be genuinely startled into 
thinking the cowboy is actually getting ready to shoot. What jerks!!!
