Why do you think that is...
IMO the Obama-Holder Dept. of Just Us and Our People will not release facts that disturb their racial demagoguery.
All these federal tables contradict their bullshit.
The FBI does have a new system NIBRS (National Incident-Based Reporting System) that does not show interracial crime but does show victim figures and offender figures by race that IMO strongly suggest the obvious.
I have both in html and I post them here. see the FR thread. The FBI NIBRS downloads (the links are in the FR thread) are in spread sheet format.
