The one simple and major thing we could do to improve the level of basic justice in America would be to get rid of the "War on Drugs(TM)". That would eliminate 70% of all urban crime in America in a single day, and there would suddenly be room in prisons for real criminals again.
But no room in medical facilities and morgues as their lifestyle pays out. Sorry, this is a conservative news discussion forum and liebertarians are not conservative. Justice is harsh. Consider the 'categorical imperative.' It is in my dictionary, is it in yours?
