It’s possible the murder rate is dropping.
It’s also possible it has nothing to do with politics.
It’s proven there is a correlation between testosterone and crime. Teen to late 20s men have the most and commit the most murders. A further factor is family size, more children per equate to generally more Crime (other factors equal like religiosity).
The US population is aging and families have fewer children. See the graph showing the projected graph of demographics by age. We are moving from a pyramid shape to a tapered column shape.
Biden has nothing to do with that but of course he will try and take credit.
Oh here is the projected one for 2060
