The contrasting images powerfully reinforced the images of the menacing bully and the innocent victim.
Some of the media’s major mistakes stemmed from stories that fit neatly into that widely accepted narrative. NBC News edited Zimmerman’s comments during a phone call to inaccurately suggest that he volunteered that Trayvon seemed suspicious because he was black. In fact, Zimmerman was responding to a question when he mentioned the teenager’s race. The network apologized for the error.
