The show pretty accurate on some of the abuses that can happen in Prison. (juvie prison perspective here) I still want to see cell phone blockers installed in Prisons. Guards are not suppose to have their cell phones in them anyways. So there is no reason for them not to install them. They install them in hospitals so this shit that it is against their civil rights is bull shit. That is what the state told me when I reported the man who killed your dad was using facebook. Thankfully the Warden though takes it more seriously.
And what they guards are not smuggling in, inmates and their friends, families smuggle it in.
