I don't have a source handy, but it was mentioned in a recent newspaper story that violent crimes in Canada have been going down over the years and are historically low, but the number of random violent attacks is up. I would guess it's probably a trend in the U.S. as well. It used to be that violent crimes were related to gang activity and personal squabbles. If you were a victim of a violent crime, there was a good chance that you would have know the person who attacked you or put yourself in the situation somehow. These days, it is often just being in the wrong place at the wrong time. These random occurrences make for more sensational news and I think it puts people on edge more, which just increases the shoot first, ask questions later mentality.
