(CBS News) Vice President Joe Biden said Florida's "Stand Your Ground" gun laws will be a topic of debate in light of the controversy surrounding the shooting of Trayvon Martin. "It's important that people be put in a position where their Second Amendment rights are protected, but that they also don't, as a consequence of the laws, unintendedly put themselves in harm's way," Biden told anchor Bob Schieffer in an interview to air on "Face the Nation" on Sunday.
