Security forces drag members of the Ladies in White, a group made up of family members of imprisoned dissidents, into a bus after a march in Havana March 17, 2010. The march turned nasty when government supporters shouted at and harassed the protesters who were rallying against the imprisonment of 75 dissidents in the "Black Spring" crackdown of March 2003.
