On Crime And Aging

I have written about this before, but a new crime where the sought culprit is 64 years old makes me wonder about the same thing again:  Have violent crimes committed by older men risen in numbers in the last decade?

Or have I just not been aware of them?  What I learned once was that crimes are hardly ever committed by the oldest age groups or the very youngest, and that the vast majority of violent crimes are committed by men in their twenties and thirties.  It could be that "hardly ever" in a high-crime country such as the US would amount to so many publicized cases in the last few years where the culprit is a man in his sixties.  But somehow I doubt that.

I suspect that there has been a real change.
