Come to think of it, we have Correlates_of_crime#Biological. It doesn't have to be about "race", it's enough to examine possible genetic correlations with increased delinquency, regardless of race. To such extent as a biological basis for increased delinquency can be established, it will stand to reason to extend the discussion to the topic of race from there.  
 If the topic has any takers, I imagine what you should look for is time preference, i.e. decreased ability to think of the consequences of one's actions.
