Yeah... Lot’s of people steal passports, but they usually don’t end up on planes the drop out of the sky. The missing passports are the key and they were obviously white. There are not a lot of Asian people with the name Luigi out there.
Not only is there a huge black market for stolen passports, European tourists in Thailand have reported being approached and asked to sell their passports (about $500) and then they can go to their embassy, claim it was stolen and get a new one. Supposedly backpackers can make a couple hundred bucks doing this. Those european guys better hope their passports were stolen - and not sold by them
