And George said that he reached for it. He may be lying.
Redial or dial...makes no difference. When Trayvon saw him using it, that’s when he probably punched him. I believe it more likely that Zimmerman already had the phone out and in his hand, since he had been using it to communicate with the 911 folks for some time.
Time and the investigation will tell. It may be completely moot if they determine there is not enough evidence to go to a grand jury.
