My neighbour showed me some photographs.
He pointed at the only man sitting down and said, "he's sitting down because he is the capo" then he pointed to "his bodyguards" and "his wife" etc.
They all looked like standard people, from like the 50's or something, black and white photo.
Turns out they used to work with Capone back in the day in Chicago. My neighbour is of Italian American descent, he said that La Cosa Nostra meant 'the thing we do' or 'our thing'. Pretty cool, as you can imagine I was stunned.

I have some other stories about London stuff but its too close for comfort.
