I don't think it is outside the realm of possibility that corporate interests would find a way to get another prisoner/guard to kill him. I doubt it would even be that difficult for them. They have so much to offer to a group of people who have been deprived of most things. solidarity to a cause only goes so far when your life is just suffering.
They absolutely have a vested interest in demonstrating to the public that people who kill members of their class will face terrible repercussions.
Yeah, but how wide is a bus compared to a Sebring?
