It's the prospect of shooting the wrong person's son that scares me like:
The son of a chemical/biological weapons developer or the son of a nuclear material handler/developer.
This guy now has nothing to lose. Like the movie Red October - some things don't react good to bullets.
It's the guy in the basement that's assembling a nuke because a cop wrongly killed a member of his family and feels that he didn't get justice. Bad decisions always come back to haunt us all !!
