It's funny how prison justice in this case would be murder yet in every death penalty discussion I've seen one of the arguments made by the anti DP crowd is that it is better to send em to prison and let them see how other prisoners treat people who did such and such.

You think they are just withholding their milk and cookies at story time or taking away their birthday?
