Prison should be about rehabilitation. It should also be for only violent criminals. Others, the poor who can't pay fines, the mentally unwell, white collar crime, thieves, they should all be working off their crimes doing voluntary work. The should have a curfew and be deprived of going to pubs and such. But in this way, they could pay for their crimes without become the bitter and hardened crims that often are released from jail.

Why Americans Don't Care About Prison Rape

What's surprising is learning that many instances of sexual assault are not committed by other inmates.

Easy one. Safety is a basic human right.

There is no such thing as a guarantee of safety, not for those inside or any of us on the outside. Safety is an illusion that sells a lot of insurance and anti-theft devices, not to mention weapons. You can be armed to the teeth and someone can just walk up behind you quietly and blow out your brains. I don't see the point of protecting the safety of criminals when we can't protect the safety of non-criminals. Those horrible things can and do happen to anybody, regardless of methods of protection.

Putting people in prison for non-violent crimes with violent criminal felons is just wrong.

I am sometimes disgusted by people online who think that being raped in prison is a routine part of the punishment for crime. I think that deliberate failure to provide adequate security for prison inmates is a violation of the US constitution's guarantee against cruel and unusual punishments.
