Is the meaning, "I think the prosecution will acknowledge that the altercation started near the "T" since the overwhelming weight of the evidence says it did."?
I don't see a reason for them to stipulate to that.
If there is a good argument for the altercation starting somewhere other than where Zimmerman said, I would like to know what it is.
what about DeeDee?
What about her?
Seriously, I don't know what you are getting at.
The timeline is problematical for both the prosecution and the defense. The prosecution's theory, as presented in the charging affidavit,
fails to explain why Martin wasn't already home by the time Zimmerman got off the phone. Zimmerman's statements don't explain why he wasn't back in his truck by the time the confrontation started. Those are the places the affidavit, and Zimmerman's statements, say the respective principals were going. As I've said before, it's like it all happened in a Zeno's paradox universe, where no one can reach a destination no matter how much time they have to get there.
So far, I have seen no sign of the prosecution revising their theory. They just might brazen it out, hoping for a math-challenged jury.
If the prosecution does change their theory, Dee Dee might embellish her story accordingly. She's got 'a couple of minutes' that are a clean slate. She can say anything happened in that time without directly contradicting herself.
If the prosecution's theory changes, but Dee Dee's story stays much the same, they will have to work around the problem. They could argue that it isn't likely Martin would detail his every move, and that Dee Dee may have misunderstood some of the things he did say.
Of course that would cast some doubt on the rest of Dee Dee's story. But it's minor compared with other issues. If the jury forgives Dee Dee for lying about the hospital, and letting Crump shape her account of the final dialogue, I don't think they'll even care that she was confused about which direction Martin was walking.
Sorry if that completely misses the point of the question.
