As for the actual ban... it feels kind of stupid and arbitrary.
Hard to say really though. It's not like prison should be a NICE expierence. Though at the same time prison rarely reforms and often just makes people better criminals... partially because they have nothing to do but get in fights, work out and talk about how they commit crimes.
As for people like this guy who are going to be in prison for life... got me. I always though maybe the family of the victims should get a say.
Then again that would kind of defacto be rewarding people who murder the family members of nice people.
Really I got no clue with this stuff.
