Crazy is a lyrically overused word not used by enlightened people. Psychiatrists resist such words that could offend or stigmatize someone. Maybe if I were a Physician that could deal with these folks in a controlled and clinical setting, then I might feel that way. But after thirty-six years in law enforcement, where I have have dealt with a myriad of people with mental disorders, I can only say that we all want what is best for that person, but I learned quickly not to turn your back to them and be prepared for trouble, whether intentional or not.
