City, state, and federal lawmakers will hold a series of hearings in response to what they have described as flawed police procedure surrounding a fatal police shooting in Queens.

At a gathering of more than 50 community leaders and clergy yesterday, elected officials said police and community stakeholders would be called on to testify starting next month to come up with a blueprint for police reform. In particular, they noted increased police aggression in the weeks since the shooting, including police interrogation of individuals who knew Sean Bell, the 23-year-old shot November 25 in a hail of 50 bullets. “The harassment of witness is being done by the police department,” Rep. Gregory Meeks said. “It must stop.”

At the same time, new information about the shooting emerged yesterday as the New York Times reported details of a preliminary police report it obtained. The 23-page report made no mention of a fourth man who may have been armed and includes the statement of shooting victim Trent Benefield, the Times reported. Notably, Mr. Benefield said Bell began driving forward and in reverse after an undercover officer opened fire on the car and not before, as some have suggested.

Yesterday, the deputy commissioner of public information for the police department, Paul Browne, responded to the article by saying: “The police department has never said there’s a fourth man with a gun.” Regarding Mr. Benefield’s statement, he said the department has never described the incident in a sequential order. Mr. Browne also denied that police are conducting a parallel investigation to one being led by District Attorney Richard Brown.

A spokeswoman for the D.A.’s office declined to comment on the police report.

In a letter to the editor published in yesterday’s Times, Mr. Brown responded to the public’s desire for quick answers in the case. “We will follow the evidence wherever it leads us, and we will reach no conclusions until all of the facts are in,” he wrote. “We will not, under any circumstances, rush to judgment.”

Meanwhile, lawmakers said the trilevel hearings are designed to bring about legislative reform of police procedure, with three levels of government involved to avoid jurisdictional challenges.

Yesterday, Speaker Christine Quinn’s office confirmed that the council will hold hearings stemming from the shooting, while City Council member Peter Vallone Jr., who heads the public safety committee, said topics could include police firearms training and an investigation of the police department’s Vice Squad.

One lawmaker involved in spearheading legislative reform after the 1999 shooting of Amadou Diallo said suggestions related to that shooting could be revived. “We have a great opportunity if we really don’t want Sean Bell to have died in vain, if we really don’t want Diallo to have died in vain,” Assemblyman Ruben Diaz Jr. said.

However, a civil rights attorney who serves as treasurer of the Amadou Diallo Foundation, Norman Siegel, suggested that lawmakers were trying to reinvent the wheel after they failed to implement a 10-point plan written after Diallo’s shooting. “My suggestion to everyone is, why don’t we have a task force to figure out how we can implement the recommendations that have already been written?” he said.
