All Trayvon needed to do was either call 911 and report he was being followed, or hightail it to the apartment which was very close by, or both.
It’s true when people say this didn’t need to happen.
But it’s Trayvon’s actions that brought it down.
He attacked an armed man who was left with no choice but to shoot him.
Zimmerman hesitated...we know that because he was yelling for help, then when no one actually came and helped him out...the witness called 911 but didn’t get physically involved...he did what he had to.
