As much as he can otherwise be detested, in circumstances like these, I wonder if the convicted perp could be put in a B.F. Skinner-style “Operant conditioning chamber”, where they could have at least some of their antisocial behavior trained out of them.
This works both ways. If he exhibits good behavior, he gets a small reward. If he exhibits bad behavior, he gets an electric shock as punishment.
An elaborate system of this kind could teach him to speak only polite English with good enunciation, including “Yes Sir” and “Yes Ma’am”. He could be shown objects he wants but are not good for him, like guns, that when he tries to grab them, he gets an electrical shock.
He could be shown pictures of gang bangers making gang signs, that if he responds to, he gets a shock. etc. Years worth of conditioning so that he *wants* to exhibit good behavior, and is *afraid* of behaving badly.
In this way he could actually get something out of his prison sentence.
It seems to me that they made a movie about exactly that once. Something about clocks and the color of that jacket...
