From what has been presented in court just thus far a juror would have to have carried into the jury her previous prejudices and biases to vote for anything except acquittal thus violating her oath as a juror and making her subject to dismissal.
There's simply no way this corrupt dingbat b*tch of a Judge in the Zimmerman trial is going to dismiss any juror who carries their own prejudices against Zimmerman. She's as biased against him and the defense as she could possibly be.
If we ever needed an example of a biased, corrupt to the core judge, Judge Debra Nelson is it. Her reputation is one of being harder on the defense than on the prosecution - indicating to me the Fed's (who are ultimately behind this case being tried) went "Judge shopping" until they got her. To me, that means the fix is in.
