The next day, police Chief Nate Harper and Mayor Luke Ravenstahl announced that the officers, without facing internal discipline, will be returned to work elsewhere in the city. Chief Harper said young people should stop when the police ask them to, and Mr. Ravenstahl called for healing.

Neither message went over well with Mr. Miles' supporters.

"We need a new chief of police. We need a new mayor of Pittsburgh. We need leadership who cares about us," Ms. Fisher said.

Speakers called on District Attorney Stephen A. Zappala Jr., who is conducting his own review of the case, to bring charges against the officers.

"To do less is to do wrong," Mr. Stevens said.

Mr. Zappala hasn't given a timetable for a decision, and his office Friday said it had no new information to provide.

Mr. Stevens said the U.S. attorney's office didn't vindicate the officers; it only concluded that there wasn't enough evidence to prosecute them for civil-rights violations.

"There is a difference," he said.

Asked for a reaction to the rally, Mr. Ravenstahl's office repeated the mayor's call for healing. Police union President Dan O'Hara said the healing won't occur if critics "continue to inflame the situation."

Police officers must make split-second decisions, Mr. O'Hara said. "They did what they needed to do to get him under control. We can't Monday-morning quarterback just because somebody's unhappy with the end result."

Ms. Fisher said another rally will be held at 1 p.m. next Saturday at city police headquarters on the North Side. A week after that, she said, a rally will be held at the Strip District headquarters of the city Office of Municipal Investigations, which produced a report on the case but hasn't made it public.
