The prison system also has the same problem with high black disciplinary problems. A study suggested higher testosterone levels were possibly the reason, because black prisoners had higher levels of the hormone.
However, race-based biological explanations of behavior are not politically correct, sociological explanations can't be discussed, and even adult criminal statistics that mirror this phenom are tossed out the window. Those doing the reporting must stop reporting black transgressions as well as try to over-report white transgressions to rectify the imbalance.
The weird thing is that poorer children of all races tend to have more behavior problems that wealthier kids. We don't have black kids here for the most part and we still have issues. And it is generally the poor kids that get in trouble.
If a higher pecentage of black kids live at the poverty level.....
But you can't get money using those stats. Make it a racial problem and someone will want to throw free government money at it. And the people who found the problem will be there to catch it.
There is a high percentage of XYY "super males" in the prison population as well. They tend to be bigger, stronger and more aggressive than the average male. I have no idea what the distribution of that anomaly is with respect to race.
