Czarivney. you stated "Fortunately he was locked up and bothered no one with his occasional schizoid aggressions." As a person who spent many decades working in Corrections, I can assure you the risk correctional staff live with being around such folk 24 hours a day, every day qualifies those brave staff as being way more than "no one".
No offense taken, but when dangerous people are incarcerated they don’t disappear, or no longer present a danger. That’s a common misperception. But try being around a whole institution of them on a daily basis, and in short order you’ll not feel that way any more. Sorry if I’ve gotten to far afield on this thread, but it struck a chord in my life.
