I think part of what bothers me is how often all kinds of tv law enforce types threaten with that and how often it is referred to as if it was just to be expected in prison, so it is made seem as if this was by systematic design rather than a catastrophic breakdown of a prison system. If it was just one law enforcement character in an extreme situation harboring revenge fantasies it would be one thing, but this makes them look as if they collaborate with this state of affairs.
