I didn't downvote you. In the past I have referred to the same table that you link. But it doesn't substantiate your point about crime rates in the 1950s because the data set starts at 1960. You may be correct, but your link doesn't show it. I would be interested in US violent crime rates in the decades before 1960 if you can find a similar table covering that time range.
