Really? Humans are humans...I always chalked this up as America had a much more intelligent Doom and Gloom propaganda machine in action. The only reason we all think Americas prison are like this is because our government controlled Hollywood says it does. Or people that have been to prison and are allowed to live and tell the governments story. Think about it, a fucking badass goes to prison and gets surrounded by some people and gets ass raped. Don't you think he is going to take it out on the first security guard he comes across? If all this raping was really happening in prison, more prison guards would lose their life...And we almost never hear that side of the story.
i'm pretty sure they keep them locked down pretty tight in those kinds of prisons, i doubt they'd be stupid enough to charge a guard.......and it's not the badasses that get raped its those lower on the food chain
racial diifferences also play a huge role, mexicans and blacks and white supremacists don't get along all that well, in russia it is all "Brotherhood" most of them know each other it's like a summer camp for them
