I don't think that is true. Below is a fairly recent FBI summary. It breaks out the murder offenses by race of the offender.
Murder Offenders by Age, Sex, Race, and Ethnicity, 2014
-- Compound that stupidity by redefining felonies into "misdemeanors," ... --
I believe that is happening. The officials want to show "success," so they engage in creative accounting. See too, unemployment statistics.
You should dig a little deeper.
I believe today that RACE crime related statistics are compiled like global warming "facts" are compiled. Computer models and random "informal" unofficial crime sources, mostly academic, never verifiable.
Try to get an answer from the FBI as to the source of their race related crime data, the reliability and consistency of all the various sources and good luck to you.
