In Rocinha, Rio de Janeiro's largest shantytown, 3,000 troops declared a victory over the drug dealers.
The CNN story begins with a scene of Special Forces raiding Rocinha Monday morning.
The troops won in just two hours and didn't fire a single bullet, and for most Rocinha's 100,000 residents Monday was just another day, CNN reported.
The operation was an effort to eliminate drug gangs before the 2014 World Cup, 2016 Olympic games, and to restore Rio de Janeiro. But still, it's a work in progress, as piles of trash line the streets and a mess of electrical wires dangle over residential houses.
According to CNN, in addition to the victory raid, Rocinha's top drug trafficker, Antonio Francisco Bomfim, was captured by police last week.
