THE line separating the good guy from the bad guy is in many cases very slim indeed. Take Anang Sumpena for example. As a member of a bomb squad of the Police Mobile Brigade (Brimob), Anang belonged to an elite unit of the Indonesian Police force. A police adjunct commissioner, he was a good policeman until drugs caught up with him and dragged him into an act which many couldn't believe him capable of: blowing up his own police headquarters.
