They’re all violent. You ever heard of someone getting stabbed non violently? Most everyone that gets stabbed inside gets multiple stabs. Multiple stabs are common in prison whether or not they’re trying to kill someone mostly due to their prison made shanks being very short for concealability purposes. And 22 stabs would take less than 22 seconds. It’s doubtful that he’ll be released back among the same crowd. (That) would definitely be criminal. However, prison is prison. Not everyone can get a single cell and even if they could, they have to let them out sometime. The SHU, the special housing unit in several prisons, keeps a prisoner in his cell 23 hours a day, in a fully lit cell with no window. They never interact with other prisoners. Can’t keep em in there forever though.
