Children on bikes block the street ahead of demonstrators who are marching protesting the death Freddie Gray, an African American man who died of spinal cord injuries in police custody, in Baltimore, Maryland, April 25, 2015. Organizers anticipated the biggest outpouring of public anger since Gray, 25, was arrested on April 12, only to die in a coma seven days later from severe spinal injuries.
