Indian guys at work assured me that the Mumbai police are unlikely to act effectively. According to them, the police there are primarily concerned with soliciting bribes from motorists, and are not famous for detective work.
May be sour grapes, of course.
Unfortunately, that seems to be the case for all non-civilized nations. This widespread corruption and lack of morality is the global cause of much of the misery in our world. Sad, but true. And how is this reversed??? The ACLU mocks Christianity, but it seems to be the basis for all rationale and moral civilization.
