This is despicable, but the conditions at the average prison are despicable too. Just watch almost any cop show to see how the expectation of prison rape has become normalised in American society.
Short-term incarceration (less than two years, and that's not an arbitrary figure) leads to much different conditions than long-term incarceration. There's different effects on humans and different changes in valuated needs.
Rape tends to be the province of those expecting little to no change in their long-term experience. A little different from murder in incarceration, in that the victim has opportunity for reprisal.
Hollywood has normalized it with their shows. I spent over 10 years in various state and federal prisons and never once was an inmate raped while I was in those facilities. I was present during 3 riots, but rapes, not.
