Metal Detectors in Major League Baseball Parks by 2015
Major League Baseball has told its 30 teams they must implement security screening for fans by 2015, either with hand-held metal detection or walk-through magnetometers.
"This procedure, which results from MLB's continuing work with the Department of Homeland Security to standardize security practices across the game, will be in addition to bag checks that are now uniform throughout MLB," baseball spokesman Michael Teevan said.
