There was once a Federal Judge in Tyler, Texas, who didn't fool around when it came to hard case criminals. Oddly enough this made him few friends in the criminal class and he received death threats on a regular basis.

And he took them all seriously. His home looked like a bunker. You could hit it with an RPG and perhaps do some damage, but it could take, and did on more than one occasion, anything up to a cal. 50.

He understood that there were very evil people in this world since he saw them everyday and when they said they would kill you if they got the chance they were not just making conversation.

More DA's and those involved with these folks need to take steps to protect themselves against this criminals. I doubt that any group has decided to go on a three state killing spree, but there is clearly no doubt that if they feel it serves their aims they would have no problem with doing so.
