the CDC has the most detailed breakdown for cause of death.
http://www.cdc.gov/nchs/data/nvsr/nvsr64/nvsr64_02.pdf
it’s all in tables 12,13. You have to scroll thru but its all there: gun deaths by accident, suicide, police, homicide is all there with breakdown by race, m/f and table 13 have non-hispanic white breakdown
the tables following 13 have death rates per 100,000 population.
the main CDC page is here, they don’t seem to have the 2014 data yet, but it won’t change much.

nothing better to shut up liberals than “CDC statistics”, LOL !
the best perpetrator data is from a DOJ household survey. I can dig it out if you want.
