Plentiful cameras, humane laws, and restless oversight.
And that's just for the violence in there. Keeping people out is another issue. Our propensity to throw non violent offenders in jail contributes to crowding and poor oversight of these prisons.
People often say we'd rather be in an American jail than other nations, such as Mexico. That's probably not true for all our correction facilities.
Honestly I have read enough news reports on many jails through American, some in little towns, and places you would never think you would hear about this kind of crap, and this shit is happening everywhere in America.
I don't think people realize just how bad it has really gotten. Unless you want to do something to get yourself thrown in jail to find out right now just how bad, otherwise you really just don't know.
In addition they had the FBI do an undercover investigation in that major prison just recently that got 7 sheriffs and several deputies arrested for trying to hide their main witness and hide evidence, then openly threaten an FBI investigator at her own home. That speaks volumes about how bad it has gotten systemically.
Then there was the huge investigation at that prison, shit was it Florida? Damn losing track of the different ones now. Anyway, point is, there has been a lot of these over the past 2 years.
