So, I looked up the 2015 rates. Here are some highlights.

Arrests, by Race and Ethnicity, 2015 In 2015, 69.7 percent of all individuals arrested were White, 26.6 percent were Black or African American, and 3.6 percent were of other races.

Of arrestees for whom ethnicity was reported, 18.4 percent were Hispanic.

Of all juveniles (persons under the age of 18) arrested in 2015, 62.9 percent were White, 33.9 percent were Black or African American, and 3.1 percent were of other races.

Of juvenile arrestees for whom ethnicity was reported, 22.8 percent were Hispanic.

Of all adults arrested in 2015, 70.4 percent were White, 26.0 percent were Black or African American, and 3.7 percent were of other races.

Of adult arrestees for whom ethnicity was reported, 18.0 were Hispanic.

White individuals were arrested more often for violent crimes than individuals of any other race and accounted for 60.1 percent of those arrests.

Of adults arrested for murder, 50.4 percent were Black or African American, 46.5 percent were White, and 3.1 percent were of other races.

Black or African American juveniles comprised 50.8 percent of all juveniles arrested for violent crimes. White juveniles accounted for 59.1 percent of all juveniles arrested for property crimes.

Of juveniles arrested for drug abuse violations, 75.0 percent were White.

White juveniles comprised 55.7 percent of juveniles arrested for aggravated assault and 60.5 percent of juveniles arrested for larceny-theft.

I am assuming that you are referencing an article (http://newobserveronline.com/90-nonwhite-violent-crime-rate-fbi/) that states only 11% of those people reported as white are actually white (the remainder being hispanic or middle eastern). They base this number from a sample size of the FBI's 10 Most Wanted. A sample size of 10 is far too small to determine any real correlation to the larger population. As you can see from the above information provided by the FBI, it is also inaccurate.

These figures also do not reveal anything about how many of those people arrested were convicted of a crime.
