Demonstrators protest against police brutality against minorities during a protest in New York, April 14, 2015.

Protesters in cities across the country marched against police brutality Tuesday, tweeting it all at #ShutDownA14. The demonstrations, taking place simultaneously in cities such as Seattle, Oakland and New York City, were organized by The Stop Mass Incarceration Network to call attention to the "murder of Black and Brown people by the police."

New York City's Office of Emergency Management noted that protest activity had clogged the Brooklyn Bridge area and recommended travelers take alternate routes.
