I agree with 1, 2 & 3...........as for 4--zero crime isn't possible even in a totalitarian state--but that doesn't mean we shouldn't strive for zero crime.
5-'inequality creates crime'--that's such a load of bull!--are you a communist? Criminals create crime and a lack of 'proper' upbringing creates criminals. There will always be inequality- deal with it
6--Just 'cos the US judicial system isn't perfect doesn't mean that we should dismiss it out of hand.......you can draw lessons from everything.
or was that post tongue in cheek?
