Less than four months into the job, Ramsey reconfigured the 6,600-member department into two main operating groups that will be headed by current deputy commissioners. The bifurcated organizational structure is similar to the way he configured the Washington police force, where he was chief for nine years before stepping down a year ago.

Deputy Commissioner Richard Ross, now head of Internal Affairs and gun-control strategy, will oversee all field operations - police on the street, the muscle of the department. He was elevated from a two-star to a three-star deputy.

Deputy Commissioner John Gaittens, a two-star deputy and veteran administrator, will be in charge of organizational support services - the "backroom" operations, such as training, communications, administration and human services.

The four new deputies were promoted internally, much to the relief of the Fraternal Order of Police, which opposed a ballot measure voters approved on April 22 allowing the police commissioner to appoint up to 10 deputies. The FOP was concerned in part that Ramsey would import a large number of out-of-town commanders.

At a news conference with Mayor Nutter, Ramsey said the reorganization would make the department more "mission-oriented." He said the aim was largely to get more officers on patrol, increasing the department's visibility to send a message to the public as well as to criminals.

"The public wants to see more cops out there on the street," he said. In the new organization, he said, "everything exists to support the patrol function."

Ramsey said he had assigned 248 more officers to street patrol. Of that number, 109 are rookies. The rest are former members of two specialized units. Those officers will now report to local commanders. "We put them in districts where they need to be," Ramsey said.

The commissioner and the mayor touted positive crime statistics for the administration's first four months as evidence that their strategy is working: Homicides have fallen 24 percent, violent crime is down 4 percent, and gun seizures are up 3.5 percent.

"These are obviously indications of progress," Nutter said. But he said his administration believed the numbers were still "far from where they should be."

Ramsey introduced his management team at a news conference after spending the morning in meetings with the more than 40 commanders who were promoted or shifted laterally.

Ramsey noted that he would not have a first deputy. His predecessor, Sylvester M. Johnson, appointed Deputy Commissioner Patricia Giorgio-Fox as head of operations, making her his clear second in command.

"I'm the one that's accountable for the operations of this department, me and me alone," Ramsey said. "What I have here is a management team, all of us working together to accomplish a mission, a goal, to make this city safe and secure. And we will accomplish that mission, and we'll do it together, all of us working together."

Giorgio-Fox, who now shares her three-star rank with Ross, will remain as a deputy commissioner. She will head a new Office of Coordination and Accountability that Ramsey said would be "responsible for ensuring that efforts of all the department's units are working together and accomplishing our mission and goals."
