Some say proposed laws can help deter gun violence. Others worry about deadly confrontations.
Instead of embracing a citizen's "duty to retreat" in the face of a physical attack, states may be taking cues from the days of lawless frontier towns, where non-deputized Americans were within their rights to hold the bad guys at bay with the threat of deadly force.
First enacted in Florida last year, "Stand Your Ground" bills are now being considered in 21 states including Georgia, according to the National Rifle Association and the Brady Campaign to Prevent Gun Violence. The South Dakota senate approved one just last week.
These new measures would push the boundaries beyond the self-defense measures already on the books. Twelve states already allow citizens to shoot intruders in their homes, and 38 states permit concealed weapons in public places. The "Stand Your Ground" laws would allow people to defend themselves with deadly force even in public places when they perceive a life-threatening situation for themselves or others, and they would not be held accountable in criminal or civil court even if bystanders are injured.
Laws putting more judgment in an individual's hands stem from people's increased concern about crime in their communities. Proponents say it helps shift the debate from gun control to crime control, and that these laws are part of the rugged individualism of Americans.
"These laws send a more general message to society that public spaces belong to the public - and the public will protect [public places] rather than trying to run into the bathroom of the nearest Starbucks and hope the police show up," says David Kopel, director of the Independence Institute in Golden, Colo.
Some critics say such "Wild West" laws are vigilante justice, and commonplace confrontations and more likely turn to violence.
"You don't just broadly paint a new statewide law saying, if you're in doubt, go ahead and shoot and kill the other person," says Peter Hamm, spokesman for the Brady Campaign to Prevent Gun Violence in Washington. "It's anathema to peace and calm in our communities."
