City Council member Leroy Comrie, a Democrat of Queens, will hold a rally today at City Hall linking last year’s police shooting of Sean Bell and this week’s shooting of Khiel Coppin, claiming that both incidents are examples of police misconduct.

“I organized this rally before the Coppin shooting, but it’s another example of police overreacting to a situation. They received a call from the mother, they saw a child clearly aggravated, clearly emotional, and they dealt with him like he was a hostile adult,” Mr. Comrie said yesterday in an interview.

Today’s rally is intended to remind the community of the November 25 anniversary of Bell’s death. Bell, an unarmed African-American man, was shot and killed by plainclothes policemen outside a nightclub in Queens.

On Monday night, police repeatedly shot and killed Coppin after he suddenly charged them while pointing a hairbrush and ignoring police orders to stop and get on the ground. Coppin’s relatives and their supporters have accused police of overreacting, but the police commissioner, Raymond Kelly, said the shooting was justified.

Mr. Comrie said he would call for better training and greater sensitivity in the police force.
