It is either a Wild West revival, a return to the days of "shoot first and ask questions later," or a triumph for the "Castle Doctrine" -- the notion that enemies invade personal space at their peril. Such dueling rhetoric marked the debate over a measure that Florida Gov. Jeb Bush (R) could sign as early as Tuesday. The legislation passed so emphatically that National Rifle Association backers plan to take it to statehouses across the nation, including Virginia's, over the next year. The law will let Floridians "meet force with force," erasing the "duty to retreat" when they fear for their lives outside of their homes, in their cars or businesses, or on the street.NRA Executive Vice President Wayne LaPierre said in an interview that the Florida measure is the "first step of a multi-state strategy" that he hopes can capitalize on a political climate dominated by conservative opponents of gun control at the state and national levels. "There's a big tailwind we have, moving from state legislature to state legislature," LaPierre said. "The South, the Midwest, everything they call 'flyover land' -- if John Kerry held a shotgun in that state, we can pass this law in that state."
