PERTH AMBOY, New Jersey—More than 250 people marched through the streets here August 25 to protest the police killing of Curtis Good five days earlier. Good, 41, was shot by Perth Amboy police officer Carmen Fazzolari after cops responded to a report of a disturbance. They are now claiming Good had cocaine in his system.

Chanting “No justice, no peace” and holding signs like the one above or saying “Cold-blooded murder,” marchers converged on the Perth Amboy police station. Speakers at the rally included Good family members and Gloria McCoy, president of the Perth Amboy NAACP.
