A pro-democracy protester holds a sign reading "down Hamad," referring to Bahrain's king, during a march Friday, May 4, 2012, in Barbar, Bahrain, west of the capital of Manama. The opposition parties that organized the march said in a statement that newly approved changes to the nation's constitution are merely cosmetic and "prove an ignorant mentality toward reforms and change."
