Re: Why not use a Mexican Bank?
Well, they used Grupo Financiero Bital, which after 2004 was bought and rebranded as HSBC Mexico, under the direction of HSBC US, so I'd imagine the reasons were "We know where you live" and "Here's a big bag of money if you just shut up and help".
It still amuses me that people think of the Hong Kong and Shanghai as a British bank - may be HQ'd here, its not a British bank.
