FILE - In this March 26, 2012 file photo, Jajuan Kelley, of Atlanta, wears a Skittles wrapper over his mouth during a rally in memory of Trayvon Martin, the unarmed 17-year-old who was killed by a Florida neighborhood watch captain while returning from a convenience store with a bag of Skittles and an iced tea, in Atlanta. Skittles isn't the first popular food brand to find itself at the center of a major controversy. The terms ?the Twinkie defense? and ?don't drink the Kool-Aid? became part of the vernacular decades ago in the wake of tragic events. More recently, Doritos made headlines when it was reported that the corn chips were Saddam Hussein's favorite snack. (AP Photo/David Goldman, File)
