Inner city blacks often go to hospitals for bad colds - expense is no issue because they're not paying out of their own pocket ... But for people who are not rich beyond words, or have great health insurance or are on 'assistance' it costs a fortune to go to a hospital emergency room... I suspect Zimmerman knew that...
Uh...because he was _arrested_? and the injury, while serious, did not warrant practical release of a homicide suspect? Can’t be in jail & ER at the same time.
