When considering the violent crime problem facing society one need understand just why someone might turn to violence rather than simply throwing them in a cage. I believe that due to a lack of understanding and knowledge society tends to reject people that do not fit into their preconceived notions of what a person should be. This rejection takes a number of forms, you might find society telling students that they are stupid and will never amount to anything by providing them poor grades, society will tell many individuals that they are not worth as much to the world as others are by giving them a low salary, score card, and not allowing them to perform the duties they might desire.
The problem here is that society has already proven several times that it does not know how to score someones intelligence or determine their value to the world. For instance Albert Einstein failed mathematics and Morgan Freeman failed acting class. Here we have two significant instances in which society determined someone a failure when in fact they were quite the success. Now we are left with a society that forces a student to obey the judgments of a society that is proven to be mistaken.
Where Albert Einstein and Morgan Freeman were able to overcome the poor judgment of society there are a great many others who are deemed undesirable by society and yet have not the ability to overcome this grave misjudgment. Society has rejected these individuals as flawed, but in truth they are not flawed so society has hurt itself by throwing away a perfectly good and useful person. In addition to this the false judgments of society can hurt the individual being judged too, the rejection offered by society hurts the individual emotionally and while people handle this differently in many cases this emotional pain turns to anger. The individual begins to both fear and hate people for rejecting him and placing him in a position for which his talents and desires go to waste, moreover he seeks to prove his capability through the act of violence.
Society is really the bearer of its own misfortune through the act of believing itself an able judge.
