Microwave Ray Gun

So the U.S. Military is testing a Microwave Ray Gun designed for riot control/crowd dispersement purposes. It's supposed to be non-lethal and allegedly causes heating and extreme discomfort to the target within 5 seconds of them being caught within the beam. The sitatuation is meant to go a little like this: "Hell, no! We won't go! Hell, no! Uh...oohh...ouch! Ok! Ok! Enough already! We'll go!"

As mentioned, the "Ray Gun" is supposed to be non-lethal and while causing pain, is not meant to cause any lasting damage to the individuals caught in its beam. However, during recent tests, the test subjects were asked to remove their eye glasses and contact lenses to protect their eyes, and also to remove any metal objects (coins, car keys, etc, objects commonly carried in a pocket by the average person) in order to prevent hot spots from developing against their skin. You know how Microwave manufacturers ask you to not put metal objects inside a microwave? That's what the military were doing; putting people in the path of a giant microwave beam. Don't we hear horror stories about poodles and gerbils being dried (& more) in microwaves by their naive owners? So why is the military doing that to humans?

I think the above mentioned scenario is more likely to go along these lines:

Rioters: Hell, no! We won't go!

SWAT/PD: Excuse me! Can you all please remove your eye glasses and contact lenses, and take any metal objects out of your pockets, and put them all on the ground in front of you. In just a minute we're going to partially cook you with a microwave beam, but we don't want anyone to get hurt.

Rioters: HELL, NO! Go and get stuffed!

I wouldn't be surprised to see Rioters turn up wearing tin foil hats, just to really prevent the Microwave Ray Gun being used against them. No, I don't think a tin foil hat would provide protection from a Microwave Ray Gun; I suspect it would enhance the power of the microwave beams, frying the guy's brain inside his skull. The guy would become a martyr, albeit a stupid, brain dead martyr, or a just plain dead one, but a martyr nonetheless, and the Microwave Ray Gun would never be used again, at least not against people wearing tin foil hats. Which would be everyone. The tin foil hat would become the choice of headwear among all discerning rioters.
