"How do these limited hangouts work?"
More or less by reporting the story but dictating the focus goes to all the wrong places. Google "BCCI" and scroll past the curiously named cricket association till you hear about a bank.
So what are you looking at? A bank in Pakistan and the UK set up by Saudi Intelligence to do dirty deeds for Pig Empire fascists and the CIA. Unfortunately for them, they got caught... using depositor money to pay operating costs and not investing it.
