i assume you mean "but when its over 90% of the time you cant argue that its not related to race"
if you're linking these things causatively to race (i.e. a thought along the line of "inherent to black people is a propensity to be harassing/whatever), and not just correlationally (plus your own biased experiences/perceptions/memories), that's simply racist
Aggression and the "Warrior gene"
A version of the monoamine oxidase-A gene has been popularly referred to as the warrior gene. Several different versions of the gene are found in different individuals, although a functional gene is present in most humans (with the exception of a few individuals with Brunner syndrome). In the variant, the allele associated with behavioural traits is shorter (30 bases) and may produce less MAO-A enzyme. This gene variation is in a regulatory promoter region about 1000 bases from the start of the region that encodes the MAO-A enzyme.
Studies have found differences in the frequency distribution of variants of the MAOA gene between ethnic groups: of the participants,
59% of Black men, 54% of Chinese men, 56% of Maori men, and 34% of Caucasian men carried the 3R allele, while
5.5% of Black men, 0.1% of Caucasian men, and 0.00067% of Asian men carried the 2R allele.
