Then check the statistics on the table "Rate of Death by Legal Intervention Involving Guns" (this table is up to 2011).

If you look at the statistics for 2011, you can see that many more white people than black people were killed by the police (i.e. 2.74 per million for blacks, and 1.28 per million for whites - there is approximately 223 million whites, and approximately 38 million blacks in the U.S.). And as I said law abiding citizens don't count (or shouldn't count), even though some people like to throw everyone, including law abiding citizens, in the statistics to "prove" that people of certain races have more chances to get killed.

In most cases its about the situation you put yourself in, not about the color of your skin.  There is cases where the police have used excessive force though of course (against both whites and blacks and any other race).
