Of Cars, Chainsaws and Guns

When a person drinks too much, drives a car and kills someone do we blame the car or the driver? Of course we blame the driver. When someone cuts off his arm, leg or finger with a chainsaw do we blame the chainsaw or the user? Of course we blame the user. When someone uses a gun to commit a crime do we blame the gun or the criminal? Whoa, different answer to this one! Why the heck do politicians and the media blame the gun?? This is sheer insanity!
