True Crime In The Streets Of Life

It's been a long time since I posted thanks to the merging of all classes but now we have to get the ball rolling on our BIG IDEAS.  Our group is looking into crime and how we will take a bite out of why it impacts our society and why the news adds fuel to it's negative effects.  Crimes have been commited in all countries with the fewest probably in Japan.  There are many different forms of mobs and gangs everywhere yet many people hardly know about their presence.  My main question I try to keep in mind is why is crime important?  I feel that if, hypothetically speaking,every human never committed an act of crime how world society be impacted?  I also want to know why different countries handle crimes in different manners?  I went to London over spring break and visited the Tower of London (which is more like a military base) and learned of all the public beheading and torture that took place.  It makes very little sense for countries to impose capital punishment to discourage offenders.  I think this in turn causes people to become more rebellious and sinister just because the governments are equally crazy when it comes to exterminating individuals.  Sometimes I feel crime is necessary for higher learning and getting one to truly look inward as to what life means to themselves.
