“You seem to forget that Zimmerman had not observed any crime and had no reason to leave his car and follow Martin in the first place.”
You are the one getting it twisted. Zimmerman reported Martin acting suspiciously, and left his vehicle to maintain visual contact so that police could find Martin when they arrived. There is no law against “leaving your vehicle”, and any reason for doing so does not have to be approved of by Rooivalk.
Do you have a source or a retraction for the allegation you made in this post?
