Violent crime rate in 1960: 160 per 100,000 people
Last year: 386 per 100,000
Crime rates are certainly down from the 70s and 80s though. Which nicely coincides with Roe V Wade decision. Many of the people who would have grown up in these bad environments with shitty parents and genes, were aborted and simply didn't have the chance to be idiots. Roe V Wade was in the early 70s, and the crime rate started dropping around the 90s, which is when those aborted kids would have been in their 20s, and fucking shit up. I'm not sure killing undesirables is really something to brag about though. Especially considering abortions are disproportionately people from minority/non-white populations.
