I have a federal felony...so I'll be sure not to count on your vote if I ever were to run for public office. Not that I'd ever court the vote of such a callous, rigid and impractical person such as yourself. These things are not black and white, and there is still systemic injustice towards various groups in the justice system or in society as a whole, such as minorities and the poor, who are disportionately convicted.
Even the courts now realize that there's many different unfortunate scenarios that can lead a person to break a law, and the judge factors one's life experiences and circumstances into their ruling. Not all laws are broken out of maliciousness or intent to harm anyone. Many crimes don't involve harming anyone (although the law can include abstract entities such as the government that can be "harmed").
So you just don't know what you're talking about. I can understand wanting to restrict violent criminals, but at that point, you might as well just incarcerate them if they can't be trusted to have the same rights as everyone else in society.
