According to Florida police, a man called 911 on Tuesday because George Zimmerman threatened to kill him during a bout of road rage. The man called 911 again the next day, claiming Zimmerman was waiting for him at work. Zimmerman was confronted by police and he admitted to arguing with the man. The police said they have not arrested Zimmerman because the man does not want to press charges. Zimmerman was acquitted in 2013 of second-degree murder in the shooting death of Trayvon Martin.
