> The Serious Organised Crime Agency claimed that "90% of all €500 notes sold in the UK are in the hands of organised
crime", revealed during an eight-month analysis. Seems like the mere existence of the 500 euro notes and those stupid enough to use them presents a pretty good profiling opportunity.
But...it doesn't. 90% of those sold being in the hands of organized crime doesn't mean 90% of times a 500 euro note is used it is used by organized crime. If most of it is used to store reserves of organized crime, it might make up a very small fraction of all exchanges of the notes (and even smaller if you exclude exchanges between organized crime participants.)
So, it might not be very a good profiling opportunity.
