Brazilians look to regional force to root out death squads

Easy to set them up. Damn difficult to get rid of them. Set up to combat Marighela 40 years ago, units within the police still offer murder for hire. They also offer "protection". "offer"? One of those you cant refuse. Comparison could be made here with the Russian "krysha" system. But it might be somewhat risky for an academic to do so! Links between police, local business and "high officials"...Organised crime nationalised, you might say.
