Yeah it sure isn't immediately obvious that this would be so, but without a doubt it is true because the same experience has occurred several times since.
So I have an escape charge in Florida (escape, not absconding) for not returning to a county work release center in Orlando many years ago. This was a really dumb thing to do because now, whenever I'm jailed I often get thrown in with the "high-security" inmates whom are also known as the murderers and anyone looking at over 20-years if convicted.
My last time through the system in Florida, I must have spent 4-5 hours a day playing chess with an alleged murderer whom was infatuated with the game and trying very hard to get better. I was in for some possession charges...bullshit really but because the old escape charge there I was.
This man had deep respect in the jail as his brother was at FSP/Raiford actually on death row for an execution-style murder committed about a decade earlier. The alleged murder this man committed was related to that very incident.
Anyway, I had played his brother for several months back "in the day" and was the only person in the jail who could beat him, and to be honest, I became somewhat a legend in C-block for my game. Remember, these people in this block often sit in county jail for 3-5 years waiting for trial and such, so the "institutional memory" actually lasts a long time in such a dismal place.
Long story somewhat short: By spending so many hours teaching this man to play much much better, he put the word out that no one was to fuck with me, and I was not only really safe, but was fed and taken care of by the group.
Very odd experience, but every word true.
