villagers using a radar gun, Just looked it up it's a decatur one

I think it's criminal how she's using the radar, swinging it around, should be held firm and only used when theres one car in the radar beam.

Ie they arnt allowed to use them in traffic, thats according to the guidelines, obviously with radar you cant single out one car so they can't prove who is speeding even if they did have a camera to film drivers!

They dont know how to use the radar guns, they also have little understanding of how they work!
