	Lasers huh?  Well, there are ways to fight this.  Blinding
	the sensor with another stationary laser is one way, emitting
	a laser when pulsed would be another would be difficult, but
	maybe possible with a wide spread laser.  However, I think the
	best solution would be the use of a laser targeting system
	on a large caliber long range weapons, such as a .300 Winchester
	magnum.  That should tend to inhibit Big Brother....
