...
	Is it true that "Laser Pulse" devices are being used to measure
	vehicle's speed for speed  enforcement purposes?
	Instead of using radar frequencies, a laser pulse reflected from
	the car is used. Naturally, a radar detector will not pick up such a
	laser pulse.
	Has anybody heard of such a rumor before? Or has anybody heard of
	speed enforcement methods other than the ones in use now?
	(NB. supposedly it's an infrared laser beam)
