Exactly, that's what I'm wondering too. Why the hell did they have to use an exposive on a pinned down guy? They could have used something not lethal to knock him out.
This is the excessive force used by police that people have been complaining about.
Yeah, they should have non-lethally shot the gun out of his hand and then non-lethally shot him in the legs so he can't run, avoiding all arteries of course, followed by giving him a cup of NyQuil to make sure he takes a nap before bringing him in.
Please stop with these fantasies that you have in your head about easy, simple nonlethal incapacitation.
