"A Transportation Security Administration worker injured in the deadly shooting rampage at Los Angeles International Airport spoke to reporters for the first time Monday, saying his first thought was to help the passengers around him. Tony Grigsby, 36, limped from the front door of his South L.A. home to a microphone stand, a brace on his right foot and cane in his right hand.... "All I could think about was helping them," he said. "I may be injured right now, but the concern really is to take care of you." Grigsby was one of three TSA agents struck when a gunman carrying a Smith & Wesson .223-caliber M&P-15 assault rifle opened fire Friday morning at the nation's third-busiest airport."
