No.
Prison is the thing I would say a lot of government has a misconception about. Prison doesn't really affect our decisions, because it's the situation that we're in presently that makes us consider or engage in such criminal activities. So if I'm hungry or there's not a lot of money and/or food in my household and if I go and get a job and work 40 hours a week for minimum wage and when I get paid, there's still no money or food in my household, I'm not really concerned that if I engage in criminal activity there's a possibility I might go to prison. That doesn't really do anything for me, because at the end of the day I've got to put food on my table and provide for my family. So, no, prison is not really a deterrent to people engaging in criminal activities.
