That is the exact example of black kids taking responsibility for their actions.
The problem is that all black youth are judged on what other blacks have done...NO ONE is saying that any person committing crime should not be held accountable. The argument is it that TOO MANY people lump all blacks together because of the action of others blacks.
Its not about Obama holding black youth accountable, its about holding all black youth accountable for the actions of some.
Personal responsibility means you are only responsible for your actions and no one else's.
