This has some data too (which shows an increase per 100K):

I can't speak for the accuracy of the FBI or Census Bureau statistics, but I don't personally accept the belief that crime rates are going up simply because people are more likely to report a crime now (in 1960 when someone stole a car or robbed a house, people avoided reporting it to the cops?).
I DO believe they are increasing at a per-100K rate.
I DO believe that all of the personal experiences of "Mayberry, RFD" represent some truth as they are from all parts of the country, not just from a group of peole living in the same town.
Statistics can be massaged and fudged, but why would it be done to make us look even worse in the world view (ain't it already bad enough that the US has 5% of the world's population, but 25% of the world's INCARCERATED population)?
