It was a “Sting-Ball Grenade”. Lets combine a flashbang with rubber bullets and CS! Probably not fun to be in the room with, but convicting him for “illegal possession of a destructive device” seems quite a stretch. I know, he’s a scumbag and we should cheer his conviction, but...

I know what you mean. We want to believe these agents did a good thing by getting this guy and maybe they did.

The BATFE are responsible for fast and furious. This was not a botched plan, it was a crime of the highest order that resulted in the needless deaths of many mexican citizens and one federal agent. This is just one of many examples.
