Prison Interviews with Murders

This is a very good look into how violence works in reality.  I would recommend watching this whole thing from start to finish.  Especially so if you are a LEO.  These are those are comfortable with violence, comfortable dealing in violence in death, they are the types of people who you need to understand exist.  They may identify as gang members or something like that, but they are just people.  Learn what reality has in store, learn about the mindset of violent people.
