I haven't read all previous comments yet, sorry if this is a repeat. GZ got out of his vehicle to try and keep visual contact. He had called police and was waiting for them to do the confronting. GZ avoided earlier opportunity to confront. When he was instructed not to follow, he stopped. He slowly walked back toward his vehicle, still hoping to catch a glimpse of TM, on the call you still hear wind but his voice is calm, normal, no evidence of running or walking fast, no shortness of breath. TM chose to confront GZ as opposed to just going home. TM got pissed by GZ "following" him, aka attempting to keep visual contact. All indications are that GZ didn't want a verbal or physical confrontation, thus calling 911. If he were an alleged vigilante, the call would've been after the fact. TM chose the confrontation route, not GZ. Keeping visual contact is not provocation or confronting. TM apparently felt empowered though not armed. The correct verdict was reached.
