Speaking of heists (see my last article about real life bank heists and upcoming films about former SOF operators here), I just came across an article about a doozy of a case involving the Italian mafia forty years ago. The crew made off with 5 million in cash as well as an additional 1 million in diamonds.
The crew had arrived at JFK airport in New York, and they had already subdued one worker, but there were another 10 to go. Fortunately for the thieves, they were well-prepared — right down to knowing the names of the employees they were about to accost.
Once the gang got inside a warehouse on the airport grounds, they systematically rounded up the night staff, according to media reports. Each of the ten were threatened with bloody violence, and as a result none resisted.
