When it's a fully grown man instead of a skinny teenager, Zimmerman doesn't stand his ground.
Zimmerman: “This man just punched me in the face.”
911 Dispatcher: “Is he still there?”
Zimmerman: “Yup. He said he's going to kill me. You need to send like three or four cops.”
911 Dispatcher: “What started the argument?”
Zimmerman: “He recognized me. He told me he was going to kill me he told me he'd (expletive) shoot me and he punched me in the face.”
