Question: were these news sources that stated that the operator told him to stay in his vehicle, the same ones that made this case about racism in the first place?
Well here is the facts:
Zimmerman therefore called a non-emergency police line to report Martin's behavior and summon police. [180] [181] During the call, Zimmerman told the dispatcher that Martin was "coming to check me out." [93] A source to the Orlando Sentinel said in May that Zimmerman told investigators that at one point Martin circled his vehicle, [Note 7] and he rolled up his window to avoid a confrontation. [177] [182]
After telling the police dispatcher that Martin "ran," [183] Zimmerman left his vehicle to determine his location and ascertain in which direction Martin had fled. [177] [184] The dispatcher asked if Zimmerman was following Martin, and Zimmerman replied "Yeah." Then the dispatcher said, "OK, we don't need you to do that." Zimmerman replied with "OK" and stated that Martin got away. [183] After a discussion about where Zimmerman would meet police, the call ended, and Zimmerman told investigators he was returning to his vehicle when Martin approached him from his left rear and confronted him.
