Yes this is a awful, will this sort of crime end? I don't think it will, if anything it will get worse. The amount of rage in some people is on the increase. I was chilling out at a small holiday destination yesterday, just down the road from me, and in the main high street there were some temporary traffic lights causing a longer hold up than normal, to add to that you have folk who think they have a right to get from A to B before anyone else, so they skip the lights, park on double yellow lines, and in turn causes more problems.
The result of this is other drivers losing their cool, short tempers, less tolerant, stepping out of their cars in a moment of madness and rage, add to this a hot day, drink and drugs, and its not long before you have a murder on your hands. We are sadly becoming a nation of greedy, selfish less tolerant, and short tempered idiots.
