PROVIDENCE, R.I. (AP) _ About 300 protesters crammed into City Hall on Thursday, demanding that officials fire and charge with murder two white officers who fatally shot a black fellow policeman they mistook for a suspect.

Demonstrators stood near the office of Mayor Vincent Cianci Jr. chanting, ``No more racist cops,'' and waving signs that read, ``Police farce.''

About two dozen police officers gathered in City Hall with some standing guard directly in front of the mayor's office.

Cornel Young Jr., 28, off duty and in street clothes, was shot Jan. 28 when he saw a suspect confronting two officers outside a restaurant and rushed outside to help.

The officers ordered Young to drop his weapon, and when he didn't, they fired, authorities said.

The two officers are on paid administrative leave while prosecutors prepare to present the case to a grand jury.

Bob Stewart, executive director of the National Organization of Black Law Enforcement Executives in Alexandria, Va., said his group feels Providence residents should wait until the grand jury acts before reaching any conclusions.

``The town needs to take time to grieve and allow the grieving process to take place,'' Stewart said.
