[Ed. – Interesting, although correlation not rigorously proven. It’s a plausible hypothesis. It would make a useful study.]
On September 30, the FBI released its annual report on crime for 2018. It showed that violent crime declined over 2017 in every category except rape, where a revised definition was applied. The number of homicides declined by 6.1%; the rate went down by even more than that, to 5.0 per 100,000.
The FBI’s good news about crime got very little publicity, and I can’t find a single publication that gave the Trump administration any credit for the trend. Why should they, you might ask, since homicide and other violent crimes have been declining since the 1990s?
Because that decline was interrupted by a two-year upward spike in 2015 and 2016, the last two years of the Obama administration. …
I conservatively estimated that the 2015-2016 increase in homicides under Obama cost more than 5,000 lives. Conversely, thousands of lives are now being saved, as the homicide rate declines.
