I dont approve at all of these stun grenades used by the cops.
Both groups are using this for their own purpose.
The police state loves this stuff.
I don't think those were stun grenades. I think they were tear gas canisters that emit a startling bang when they are deployed. But they are not bright or loud enough to incapacitate the way a stun grenade does.
Not to say that means you should support the use of this type of tear gas canister, of course. It's just a different critter.

When it happens to a group of Sarah Palin supporters at a book signing, maybe they will finally get it.
