You hate to say it about anyone, but I’ll bet nobody isn’t glad He/She is gone. Sounds like a bitter confused, mentally ill miscreant that tried to make everybody else miserable too.
Not bitter, but perhaps selfish: He made ADA demands of local "scraping-by" restaurants, which contributed to his unpopularity.
The camera was sturdily mounted on his wheelchair: the object of his photography was primarily Florida butterflies, a subject in which he was expert. He had loyal friends, all of whom were Liberals: one friend moved from the Keys last month. That friend demonstrated every Saturday against the Iraq War. (But only while Bush was President).
One can suspect that all the medications, the van, the oxygen, the motorized wheelchair, and the operation itselfwere charged to the VA. I can't recall if he ever spoke of his service.
