I don't like these cherry picked videos because there is no way to know, from just what is presented, if it has any merit. Obviously we here all know from a lifetime of experience that this is a valid commentary on racial differences, but it is itself a very weak argument. I'd add that it's not just the proclivity to react violently that defines the differences. Look at the home. The way the mother speaks to the child. I can already hear the leftists blaming poverty for the behavior rather than aknowledging that low IQ explains both.
