About the type of comment I would expect with somebody going by your screen name.
You do realize that your philosophy pretty much ensures that people convicted of any violent crime will commit a subsequent crime, right?
Here let me do the logic for you:
I commit a violent crime when I am 17. I do my time and get out and try to live a productive, crime free life. But nobody will hire me to work, because I committed a violent crime. Hmmmm? What should I do for shelter, food, and all forms of basic subsistence? Well, how about crime? At the worst I will get caught and be able to get three squares and a cot.
