When you get close to one it send a signal to your roadangel, snooper, whatever to warn you. The ones that detect guns pick up the laser scatter as it bounces off the car in front, then sends a signal to jam the transmission as you go past. The gov't is trying to make snoopers etc illegal saying that people use them and slow down when they get to a speed camera. I personally thought the whole point of speed cameras WAS to slow people down...
I hope that's the layman's version cuz otherwise I'd hate to point out "the little box on the dash" actually does nothing of the sort...
And what's with the car in front? I've never needed anything in front to detect something on any of the K-bands or the laser...

Theoretically yeah it is. Though I think they'd just guess until they were travelling in the same direction basing their assumption on the movement of traffic around you...
