What surprises me is how much people think TV represents reality. There are more truly sadistic, demented, amoral (no morality), totally brutal, violently insane, and people who find pleasure in causing others to suffer than most people imagine could exist - and believe it could never happen to them and theirs. What does 900,000 missing persons per year mean to you - and that is just those reported and for which the police file a report. Add to this all who do not go missing, but are only violated and abused?
The story of that police officer is not some unheard of anomaly in terms of sadistic, murderous bizarre violence merely for the pleasure of doing so.
What to do with such people? Kill them like the rabid mad dogs they are. But I'm won't get my way.
