This is true. But the root cause is the breakdown of the nuclear biological family which has left black boys (and girls) without ever-present strong male role models. Now of course this breakdown which was first pointed out in the 60s has spread to every other demographic.
Basically the unintended consequences of the great society programs is that American parents have farmed their responsibilities out to others, usually the gov't. Simultaneous with that those same parents have willed themselves into perpetual adolescence. There is a special irony when NCHawker calls for more government programs to fix a problem largely caused by government programs that encourage/enable a lack of personal responsibility.
Wow are you way off the target blaming the govt and the Great Society and trying to deflect blame away from the individuals who commit crimes.
We all just need to realize that there are bad people out there or to put it another way a lot of people who will do bad things to other people and/or property.
There are a lot of young white, black, and other people of color who grow up in rough or bad situations without a parent lets say and these young people are good people. Perhaps there is a more deep biological reason for the agression and narcissitic behavior of some males as in as simple an explanation of their testosterone levels. There have been studies of the birth order of sons that show lesser agressiveness from the first born male to a third or fourth born male which can be linked to the mother's body suppressing testosterone levels of the fetus. Perhaps it is reasons like this rather than if the Great Society let everybody down or made people not have to own up to their own responsibilities.
