FILE - In this March 27, 2012 file photo, Steven Jonhson, 3, holds an enlarged banner of "Skittles" candy, as he joins Los Angeles community members at a "Justice for Trayvon Martin hoodie rally" in honor of Trayvon Martin, the unarmed black teenager who was wearing a hoodie on the night when he was shot and killed by a neighborhood watch captain George Zimmerman. 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/Damian Dovarganes, File)
