and the occasional 'cell warriors' who talk tough when their cell is locked and nobody can get to them, but when it's time to hit the rec-yard, or somebody calls their bluff, they go running to the C.O. and ask for P.C. and debrief as quick as they can.
and like in prison, you'd better be everything you say you are and better have done everything you say you've done, because people will absolutely find out, and then when you lose that respect, it's gone forever.
oh, and 'confidential informant's' are never 'confidential'... ever. your name is always in somebody's paperwork (or PM's). always.
