I find it a bit appalling that this guy got 22 years for robbery. Had he killed the guy, he would have got only a little bit more time. This sentence is disproportionate and does not serve the public at all. Now the tax payers are forced to support this guy for the next 22 years at a ridiculous cost. When he gets out, they will likely have to support him some more given the lack of training in prison, and opportunities afterward. If this guy had kids, this sentence could potentially alter the children's lives toward a life of crime too (though that is speculation, but statistically supported).
Why not put the guy in prison for a year, with intense training, followed by 5 year years of probation. After leaving prison, his record will be sealed, and if he is well behaved on his probation for 5 years, cleared. Something a bit innovative. No one is being served by this guy going to jail for 22 years for a simple armed robbery.
