Racial Profiling on Traffic Crimes and Racial Profiling on DNA

“Motor vehicle searches are a possible application of racial profiling. In the United States black drivers are much more likely to have their car stopped and searched than white drivers. One explanation for this observation is that police officers have a racist preference, making them more likely to search a car driven by a black motorist. An alternative explanation is that police officers target not race but certain characteristics that are only correlated with race. This is also related to the hypothesis that police officers have no racial preferences and only maximize the probability of a successful search. If black motorists are more likely to carry contraband or illegal drugs, racial profiling may lead to a higher probability of successful searches.[1] “

Being black is an apparent genotypic trait and %100 defined by genes. When DNA profiling will be cheap enough in the near future we can take a look at the DNA profile of a person and say “Oh yes, this person is colored”.

However, based on the “black genes” can we say this person is more likely to commit crime ? Do people commit crime because of the skin color genes ? Where does the gene profiling end and where does the social profiling start ?
