Martin was looking at a townhome that was recently broken into and suspiciously wasn’t in a hurry to get out of the rain. He then approached Zimmerman and circled around his truck as Zimmerman was sitting sitting in it. As Martin kept moving Zimmerman called the police and then walked to try to see where Martin had gone. Zimmerman was ambushed while he was walking. I would hardly call that chasing.
Zimmerman also passed a voice stress analysis when he was asked if he confronted Martin (Answer: No), and whether he was in fear for his life (Answer: Yes).
It’s so easy for idiots with microphones to ignore the truth.
