Now let me see if I have this right.
There's no guidance or discipline in the home. The family situation is so unstable, 'Junior' doesn't even know where or to whom to send a Father's Day card. Junior gets dumped into the education system where he is socially promoted because the overwhelmed school district can't deal with the undisciplined whelp. Junior's major formative influences are 'gangsta' rap videos and a corresponding peer group of gangsta wannabes. At age 18, Junior is turned loose on society carrying a bad attitude, a broken compass, little respect for authority, and maybe even a gun. Junior then gets himself in big trouble with the law and meets dire consequences.
And the situation diagnosis is that the police need more training and understanding?
