In the 911 call, Zimmerman said that he was following Martin, despite the operator’s suggestion that he not do it. Neighbors also said that Zimmerman was specifically interested in the black people in the area.
911 “operators’ often tell someone in the midst of a home invasion to not shoot, “the cops will be there soon (well, as soon as they finish the last donuts)”. 911 “operators” are sometimes FOS!
