It shot up during Obama's tenure, especially crime in Chicago and Obama took no position, said nothing, did nothing to ameliorate the problem. Gun violence has not increased in 6 months of Trump.
as far as the number of mass shootings it has decreased big time. when 0bama was president there seemed to be one every other month. Thank you President Trump.
Decreased so far in Chicago, but probably because the shitheads are all dying. As for other cities, it's on the rise. Baltimore, Minneapolis, New York City, Milwaukee, Philadelphia, D.C., not Trump's fault, it's the fault of the loony liberal mayors.
Gun violence has been decreasing for a long time, but premeditated mass shootings are up. Conservatives will blame Obama and credit Trump, but the reality is significantly more complex than that.
