Redacted (or WKMG self-censoring) Zimmerman saying what Martin said on first approach.
Singleton wondering why Zimmerman got out of the car if he was afraid of Martin. Instead of a conversation, you put up your window, then when he runs, you follow him. He may be afraid, and you don't know (she suggests). You never told Martin who you were. You could have told him, instead of putting up your window. Z: he wasn't in earshot, and I didn't want to confront him.
