What's in store for protesters?

I gaurantee you that it was on the wussy setting for filming.
If used at full steam it would be able to travel through wood.
It supposedly can't travel through a conductor.

As with anything there is always a way to beat it. Ive seen some very interesting counter measures first hand with this weapon that the people who designed this gun know will beat it. Or you could just take it from your oppressor by sheer force and then its yours.

It's microwave; it can be blocked the same way your microwave oven keeps the rays inside.

In fact, much like the metal shield in the door of the microwave, you can even have holes in the material, although you have to know the specific wavelength at which the microwave operates to know how safely large the holes can be.

As for charge building up in the shield—someone else can probably correct me on the physics, but I don't think it's the microwaves in the oven that cause the electrical discharge from metal surfaces, it's that the spinning electromagnet that's used to create the microwaves also causes current to flow in metal. So I don't think this would be a concern in this context, although keeping it grounded just to be safe is certainly a good idea.

Making a (relatively) small EMP "gun" is doable. The main problem with it would be the range. Being small enough to be portable will limit the range. I'll have to think about just how limited the effect would be considering other factors. If anyone is really interested, I'll take some of my (not so) copious spare time and work up the circuit to do it.   I'll even post it if anyone cares to give it a try, all caveats for taking personal responsibility for doing the project on your own and releasing me from liability would obviously apply. 

On blocking microwaves (or other transmitted electrical signals)... think "Faraday Cage"...
