A police officer douses a man, who was hit by pepper spray after defying a curfew, with water as he lies detained in west Baltimore, Maryland May 2, 2015. Thousands of people took to the streets of Baltimore on Saturday as anger over the death of young black man Freddie Gray turned to hopes for change following swift criminal charges against six police officers. There was an upbeat mood at the march from the housing projects where 25-year-old Gray was arrested last month to a plaza in front of city hall where the city's chief prosecutor announced charges on Friday ranging from murder to assault in his death.
