NBC News Miami reports: They are showing up like never before. Guns at South Florida airports are being brought by passengers now in record numbers, officials said. The disturbing number of weapons the Transportation Security Administration is finding at checkpoints comes as the Federal Aviation Administration is dealing with an increase in unruly passengers and just before the busiest travel time of the year. That’s a potentially dangerous mix the security experts want to avoid. "It is a concern, both the unruly behavior that we’ve seen and the number of firearms,” said Daniel Ronan, the TSA Security Director at Miami International Airport.
