There are some who believe that Dee Dee is an invention of Mr. Crump, or close to it.
If this is the case, Mr. Crump's career could be in jeopardy. In a state that has a non-joke legal system, anyway.
Also, most of what little momentum the "Convict George" locomotive had resulted from the mumblings and stumblings of Dee Dee, under the careful (and helpful) questioning of Mr. Crump.
We’ll see but ultimately it is most important that witness 8 be contradicted. So they are using Crump to fill in blanks of his interview with witness 8. It doesn’t seem he will say anything that contradicts her story. But we’ll see.
There are no eyewitnesses to what happened other than George Zimmerman himself. There are some neighbors who heard the noise. Zimmerman has a constitutional right to be confronted with the witnesses against him--who are in effect Dee Dee and Crump. O'Mara should be able to cross-examine them. Judge Nelson knows what verdict she wants and doesn't want to be delayed with such technicalities.
Unfortunately, even if Zimmerman is acquitted, he will probably have to live in hiding for years or else be murdered. If he is sentenced to prison he's likely to be killed by one of the inmates.
