Re: Indian Photo ID scam
I won't go into details, but I entered a country (multiple times) with somebody else's ID. Basically only one of us had a visa so we all shared his passport. That he was Asian and most of the rest of us Europeans did not seem to trouble the immigration guys in the least.
I also nearly left a different country on someone else's passport, a woman twice my age that I didn't know at all. At some point she must have noticed and gone back to the immigration people who eventually found me at the boarding queue.
