This is one of those things I don't consider a transgender issue. Jails, prisons, etc should allow each cell to have a maximum capacity of one. Fact is that not everyone convicted is guilty but many in the system are dangerous. Heck all meals should be taken in the cells and convicts should not have to go to yard time if they don't want to.
The downside of “cells of one”, is people who get suicidal. In civilized countries, new inmates get paired with a “trusted inmate” for the first couple weeks, both to show them the ropes, but also to prevent them from hanging themselves with one.
Im not so sure in the US system that cell mate will prevent suicide. I also do not see suicide as nearly as bad as getting killed by your cellmate. At least the suicide wanted to die and made that decision.
Yeah… from the descriptions of this case, it seems like it was more of an execution, with other inmates high-fiving the killer as he was beating the victim, and personnel conspicuously absent for over an hour even as it was being recorded on camera.
Then again, there was the Epstein case, where he was “left alone” and just the cameras and all checks “happened to fail” all at the same time.
