Concert Security Guard Would Willingly Give His Life To Protect Coldplay
CHULA VISTA, CA—Twenty-four-year-old security guard Ian Moran told reporters Tuesday that he would gladly lay down his life to protect the members of Coldplay during their upcoming show at the Cricket Wireless Amphitheatre. "I hope it doesn't come to that, but if [lead singer] Chris [Martin] is in danger, it's my job to take a bullet for him if I have to," said Moran, who has been struck in the head by beer bottles on three separate occasions while protecting Good Charlotte, Ozzy Osbourne, and Sheryl Crow, respectively. "A secure Coldplay concert is bigger than just one man." Coworkers said Moran started taking his responsibilities very seriously after a 2006 show at which he was unable to prevent overzealous fans from stealing Tim McGraw's cowboy hat, an incident for which he has never forgiven himself.
