So why would the prosecution want her as a witness at all. They can't possibly think that she would help their case in the least. I think they did it because she is a Zimmerman after all and this further disparages the Zimmerman clan.
Then they would use her testimony during sentencing. They will not..should not...be able to use her in the case in chief.
