Mayor Bloomberg: End “Stand Your Ground” Laws – Bloomberg will join the Rev. Al Sharpton in Washington D.C. Wednesday to announce a national campaign to repeal the controversial laws, which in general hold that a person has no duty to retreat when attacked.  Opponents of the laws, however, say they should really be called “Shoot First, Ask Questions Later.”  Florida’s “Stand Your Ground” provision is at the center of the firestorm surrounding the shooting death of Trayvon Martin.
