“It seems clear enough that Zimmerman precipitated the whole event no matter who struck the first blow.”
Was he dealing with a trespasser? If so, then therein lies the precipitation of the event. If not, then I agree with you wholeheartedly.
Last weekend five people were killed in Chicago - among them a 7-year-old girl, who was playing outside her house - and 12 people were wounded by gunfire... Where was Obama’s stand on that?
