War Of The Worlds

This is scary.
The yanks have developed a "non-lethal weapon" for riot control called A.D.S. or Active Denial System. Basically it's a heat ray that sends out a beam of approximately 54 degrees centigrade from as far away as half a kilometer. A bit like a long range microwave. Now this is all well and good, but it occurs to me that if they can set the system to deliver a beam at 54 degrees, then it would probably be easy to get it to deliver a beam at 500 degrees. Scary stuff.

Why can't America be more like Canada?
