"They probably thought we were going to leave like usual," Cunha said from the school, which has become the headquarters of Rio's latest experiment in urban policing. "But this time we're staying."

The police have regularly launched large operations in Brazil's favelas, or slums, in their battle against drug gangs over the years, but authorities say the occupation of Santa Marta, a relatively small, contained neighborhood, is part of a new approach, a pilot project for the future of crime fighting in this violent city. Brazilian police officers are attempting counterinsurgency tactics similar to those used by U.S. soldiers in Iraq -- setting up small bases occupied around the clock inside violent neighborhoods, developing intelligence by living among their adversaries, and using government funds to rebuild broken areas and generate goodwill.

"Santa Marta is like a laboratory for policing a conflict area," said Antônio Roberto Cesário de Sá, a senior official in the office of the public security secretary of Rio de Janeiro. "The idea is to rescue a territory that until now has belonged to a drug-dealing gang."
