Chants of "no justice, no peace, no racist police" echoed through the streets of Baltimore yesterday, during a march that organizers billed as a "victory rally" coming one day after a prosecutor charged six officers in the death of a black man who died in police custody.

Earlier, state’s Attorney Marilyn Mosby charged the six officers with felonies ranging from assault to murder in the death of Freddie Gray. Gray died from spinal injuries one week after his April 12 arrest. The death provoked riots on the streets of Baltimore and quickly became a rallying cry against police brutality and social inequality in the city and elsewhere, according to protestors.

The march was planned to be a mass protest of Gray’s treatment by police, but after Mosby’s announcement, the tone of the demonstration changed to more of a celebration.
