Let's Get Out Of This Country

I was watching a report on CBC's The National the other day which said that Scotland leads developed countries in incidents of violent crime. The National report focused on the current knife culture that exists in Glasgow. Glasgow in particular has a long history of gang violence going back to the 1960's. With much of the violence resulting from persons coming from the most impoverished parts of Glasgow it's really no surprise why gang violence happens. What's surprising to me is that, looking at another example, Compton(California) can give birth to N.W.A.(a natural reflection of the environment from which it comes from) but Glasgow is quite the opposite in the bands that it's spawned such as Belle and Sebastian, Camera Obscura, The Delgados, Franz Ferdinand, Aztec Camera and scores of others. What is the connection?
