You not only profile, you are wrong.
According to 2004 government statistics, 38% of felonies were commited by blacks, 58% by whites, and 3% by other races.
The government tables lump Hispanics with whites, so that is a bit misleading. However, 70% of crimes are NOT commited by blacks.
Blacks comprise about 14% of the US population, Hispanics 19%.
