That would absolutely suck to get a taxi and to then get robbed. It reminds me of an episode of the Simpsons when they travel to Brazil and Homer is took hostage in a Taxi.

I know next to nothing of the excistence of an Argentine Mafia, maybe you could enlighten us all here with some information and knowledge. I know Brazil has had it's connections in the past with Buscetta, exiled head of the Cupola, being found there even after numerous slayings of his sons and other relatives back in Sicily. He controlled huge drug connections between there and America.
