Who Is Daniel Pantaleo, Eric Garner's Killer? NYPD Officer Must Be Fired From Police Force, Twitter Users Say

A Twitter campaign was underway Tuesday as calls grew to fire the New York City police officer whose chokehold killed an unarmed black man selling untaxed cigarettes in 2014. Daniel Pantaleo employed the chokehold after he said Eric Garner was resisting arrest for selling "loosies," or single cigarettes, in public. The entire deadly episode was captured on video by a bystander but a grand jury failed to indict Pantaleo.
