Look at the pie charts 
75% of White civilian gun deaths are SUICIDE
85% of Black civilian gun deaths are HOMICIDE by other civilians

It's with noting that only 2%  of Black gun deaths are due to legal intervention by cops

The USA has a black POVERTY problem,  not a gun problem so fix the schools and gun violence mostly goes away. 
It's sad to say but combine Two bad weekends in NY, DC, LA, Philly and you match the concert deaths totals.
