This Week in Bans: Park Slope Parents Decry 'Tempting' Ice Cream

Welcome back to our weekly look at what's been outlawed in cities across the world (last week's edition here):

• To prepare for unruly protestors at the 2012 Republican National Convention, Tampa mayor Bob Buckhorn is drawing up a list of things that the police will treat as "security threats." On the list: BB guns, water pistols, masks, pieces of string longer than 6 inches. Not on the list: Actual, bullet-shooting guns. Buckhorn's hands are tied when it comes to banning these popular weapons for assassins because Florida law mandates that "any local ordinance that regulates guns is void," the city attorney told the Tampa Tribune. While the Secret Service will take away the guns of conventioneers who enter the event's inner sanctum (let's hope not from their cold, dead hands), anybody will be allowed to pack heat in the outer "clean zone." Protest signs, however, are still forbidden if they include wood sticks larger than a ruler.
