Just days after Brazilian police surrounded the drug gang stronghold of Complexo do Alemao in Rio de Janeiro, making several high-profile arrests, questions are being asked about whether the operation was a successful one  

Authorities also confiscated drugs and thousands of weapons in the favela but the majority of the estimated 600 drug traffickers appear to have escaped the crackdown.
