I think that "violence begets violence" and as far as this saying is from a solution to crime, we should never forget it. My country New Zealand has relitivly little violent crime and I think this is because a) we have strict gun laws and b) our leaders are benevolent and attack social problems at their roots instead of turning criminals into a profitable business like the US seems to.
I think that the law is an important process and vigilantes who ignore it are no better than the crims. If everyone took the law into their own hands there would be chaos.
Hollywood is another medium that I think ignores reality and whats best for society in favour of what is most profitable.
I recently saw the movie The Brave One in which Jody Foster plays the role of a violent crime victim and turns vigilante. Vigilante movies have been around for a long time and they seem to all do well at the box office so Hollywood keeps making them. I like them as well and it makes me ask why? Do you like them? Perhaps there are millions of people who would like to see some of the worst criminal element in society dealt with this way? I imagine many of the victims of such crimes do. Perhaps millions are fed up with seeing violent criminals let go due to some breach of "technicality" in the law that allows some high priced lawyer to get them off? What are your feelings? If you were on the jury of someone like Ms Foster played in this movie would you convict them or set them free? If the same thing happened to you , or someone you love, and the law set the person free what would you do?
