That is what the police are now saying.I don't know that Zimmerman did initiate the fight. Please show me this "All evidence points to Tray initiating physical contact and punching Zimmerman" because I'm not seeing it.
You have to remember the timeline on all this. Initially there was a lot of speculation in the news media about what exactly happened. The police plainly stated that the media's sequence of events were "purely speculation." It wasn't until a few days ago that the final results of the investigation began to be leaked to the media. When they began asking the police about it, the police then acknowledged that all 911 audio, eyewitness testimony, and physical evidence backed up Zimmerman's story. But up until then the police weren't saying very much past their "official" statement and answers to questions issued by the city manager, which was still pretty good.
What we know now, about the investigation, the incident, and Tray, is a lot more than we knew three or four days ago.
