Many kids get punished for talking back to their parents with loss of TV privileges yet murderers, rapists, and thieves get to sit down and enjoy TV daily. When someone is incarcerated they should be spending their time paying back their debt to society through work programs and times of meditation and reflection. There should be limited recreational time and any that is allowed should not be spent in front of something that does not benefit them in their rehabilitation.
The boredom that would be rampant in prisons if there were no tv would not help us reduce violence if a prisoner were to be released. And it can be helpful to keep current on what is going on. However, content needs to be monitored for violence and maybe only selected programs should be allowed.
