Shes biased partly cause shes scared. Nothing to stop them from coming after her if theres a verdict favorable to Zimmerman. He will have a price in his head, so will she, and the jurors. Its a no-win situation.
Interestingly, they will have plenty of evidence to support their justification. This administration is creating more Timothy McVeighs every day.
So... is TM or GZ in the role of Crispus Attucks this time?
