It doesn't take much.
Psychologist determines when he's removed
It doesn't matter where he is housed, special housing or not because the ability to kill yourself in either cell is the same. 30 minutes is plenty of time to be dead. It really doesn't take much, just determination. What did his cellmate have to say?
They love the overtime. What you need to look for is how many mandated overtimes were there. HUGE difference.
Do they care, yes and no, mostly no. Some what of yes because you've got the rest of the feds and admin crawling up your ass now trying to figure out who to pin it on.
Lots of suicides result in punishment. It depends on if you did your rounds and paperwork or not, it's all on camera. Then gets reviewed for that event and actually even the days leading up to the event. Someone is gonna get nailed for it, someone always does unless they did their at least their bare requirements.
Actually, it'd be EXTREMELY difficult in his situation. Plus mexico and america, totally different places and mentalities. In America, there is redundancy to ensure things don't typically happen unless staff really fuck up, even then it takes several staff to screw it up. It'd have to be orchestrated and well.....most staff are not talented enough to pull something of this magnitude off.
