Excellent point. Every good defense attorney should be constructing their closing argument after each trial day. The point you just made needs to be emphasized in the closing argument, especially since the prosecution team led off their opening statement with Zimmerman's words.
And, by the way, The Today Show should apologize to its viewers each and every day they cover this story. Their deceitful editing of Zimmerman's phone call to make him look racist caused great harm to his ability to get a fair trial. Turns out Martin was the racist, not Zimmerman. But I doubt NBC will be acknowledging that. The NBC peacock is no longer colorful. It's just black these days.
GZ's lawsuit against them on just that matter is intended to force them to acknowledge it with a six-figure payment.
