As a result, readily available information and communication, along with a strong economic development and a general revitalization of infrastructures in many areas, reappropriated many districts and substantially reduced crime across the city and state as a whole.

called the unidade polícia pacificadora - upp (pacifying police), this special law-enforcement group has successfully made the largest favelas significantly safer in rio.

one immediate effect was the significant reduction of thefts in copacabana and ipanema, since the would-be robbers now could not run and hide in the nearby favelas.

the military police's elite squad bope is another important institution - credited for helping combat crime in areas of rio previously deemed as unrecoverable. additionally, the city has developed real-time video monitoring systems via remote control centers, permitting continuous overseeing of some of the most important parts of town.
