If you go over the posts from a few months back, Gov Rick Scott(Florida-R), set up a special task force(led by Lt Gov Jennifer Carrol, a retired US Navy officer with a A+ rating from the NRA).
The task force findings based on several months of meetings, research, statements, open forums, etc said the Florida Stand Your Ground(gun laws) were okay & less violent crime occurred in FL after these laws were put into the books statewide.
Carrol later quit her post after a scandal not related to the Stand Your Ground task force report.
Id add that a defense atty & media advisor for Fox 35;
www.myfoxorlando.com said on Sun, 07/14/2013 that she didnt think a DoJ/CRD case will go anywhere.
Her reasons were GZ & his family were under intense scrutiny by the FBI for weeks. These special agents couldn't find any solid proof of Zimmerman's racist or bigoted history. The DoJ wants to stay quiet but the reports & documents will surface at some point.
In my view AG Holder will let this run in circles then let it slip away like the Fast & Furious scandal.
