No offense, Jace. But prison guards aren't generally the sharpest knives in the drawer. No offense to your family. I'm sure they're all bright enough. I'm just speaking in general terms. I never met a hack who wasn't an imbecile or a steroid head. Or both.
I don't think it's really correct to generalize that way. There have been prison guards or directors of prisons who had been killed by organized crime for threatening the system of privileges for mafia bosses established inside the prisons, they weren't stupid at all if they managed to bring the entire system under threat. For example, Giuseppe Salvia killed on orders of the camorra boss Raffaele Cutolo or Sergio Cosmai killed on orders of the 'ndrangheta boss Franco Perna.
