That jives with what was on the video. Now if the caller is for real or not is the question. If she is there will be a ton of pressure on her not to say anything. Snitches get stiches.
Some questions:
1. Is this person a real witness or a pretender?
2. Will they be willing to testify in court?
3. What color are they? Something tells me a white witness would [somehow] get disqualified.
Whatever happens in the end, Wilson (like Zimmerman) has been judged guilty in the court of public opinion.
She's not an eyewitness.
