Furio, that seems to correlate more with what we know. Mukremin is a great organized crime poster and chart-maker, but I don't think he has ever admitted to knowing more than the feds or other acclaimed sources. He is simply an organized crime researcher who specializes in making charts.
So this chart here is, again, not any sort of admission or evidence that the Buffalo crime family is still active. Far from it. Don't be mistaken that it is.
