Welcome to Florida, but beware of the natives. A national gun-control group has launched an ad campaign to that effect, warning visitors not "to argue unnecessarily with local people."

"If someone appears to be angry with you, maintain to the best of your ability a positive attitude and do not shout or make threatening gestures," according to fliers from the Brady Campaign to Prevent Gun Violence that were being handed out last week at Miami International Airport.

The information campaign, which has riled the state's powerful tourism industry, was created to protest the state's new "stand your ground" gun law. The law allows Floridians to use guns or other deadly force in certain circumstances without first trying to escape.

Gov. Jeb Bush (R) has labeled the tactic "pure, unadulterated politics"; defenders of the law say it will make the state safer.

"It's an education campaign," said Peter Hamm, a spokesman for the Brady organization, who considers the tactic a success.

The ad campaign started last week with newspaper ads in Chicago, Detroit and Boston as well as the fliers distributed at Miami's main airport. The group is expanding the newspaper ads to London and has set sights on a couple of billboards in the Orlando area.

Miami airport arrivals are given fliers telling them to be cautious with the locals.

Critics of Florida's new state law call it the "shoot first" statute in the flier.
