Because of all the national media attention and 'outrage', why don't they just take the evidence to the Grand Jury with a manslaughter charge? If the Grand Jury refuses to indict Zimmerman, then so be it.
Not sure, but my educated guess would be because Zimmerman could sue the crap out of them. The DA recommended no charges due to total lack of evidence. Are you suggesting they should have ignored that and just railroaded a possibly innocent man because of some phony, trumped up outrage. That's like giving in to terrorists. Not right.
