Mayor Takes Anti-Illegal Gun Campaign to Fla.

Mayor Bloomberg is taking his nationwide campaign against the illegal sale and trafficking of guns to Jacksonville, Fla., where he will speak today at a conference arranged by the organization he co-founded, Mayors Against Illegal Guns.

The mayor of Jacksonville, John Peyton, is attending the conference, which will be held at the Jacksonville Main Library. An aide to Mr. Bloomberg declined to provide further details.

Last month, Mr. Bloomberg and the mayor of Baltimore, Sheila Dixon, announced that they would build a regional database to track guns used in crimes. The database would be made available to police departments on the East Coast and aid law enforcement officials working to track and crack down on the illegal trafficking of guns. The coalition, which Mr. Bloomberg founded in 2006 with the mayor of Boston, Thomas Menino, is planning to host a national summit in Washington next month that would bring together mayors from across the country to talk about guns that are sold and trafficked illegally.

There are more than 250 mayors from more than 40 states in the coalition.
