" It's too pat, almost rehearsed in a fashion."
Yeah. That stuck out as me as well like a sore thumb, right from the beginning. He was saying that to the EMT, and he expressly said it so loud -- he wanted to be sure it was overheard by the cop.
Knowing full well he knew the ins and outs of the law (besides having attended Police Academy himself, having his father and mother in the court system - he almost literally was bathed in the details of the law his whole life) ,
...and the the way it would go down if it was to be a claim of self-defense in court, he seemed to go out of his way to make sure he got that on the record loud and clear.
And having the CCL, he would have had to know the law on using force.
That was my initial reaction. I do believe that Trayvon struck Zimmerman, although I don't believe anyone can say for sure how it started. So it's possible that Zimmerman was yelling, but IMO it was Trayvon.
Oh ... something else in that CNN link. At the end of the video report, a "senior law enforcement instructor" addresses the timeline and the police report, and that the maximum amount of time Zimmerman could have been treated by EMS was about 8 minutes.
