They committed the crimes. Hollywood may exaggerate things, but the basis is true. The neighborhood where I grew up and returned to was and is relatively safe. It's a middle class area, private houses. They may have been neutered to a degree and not what they used to be (insider trading, etc, is their current gig. Contract Albanians for dirty work, etc), but they still are the biggest criminal organization round, even with upcoming Russians, Chinese, and said Albanians.
Where I had an apartment for 20yrs, Arthur Ave, social clubs still abound, tho more Albanians than Italian. Bodegas won't sell pot round there like they do in other neighborhoods because the Mafia won't permit them, even tho Italians are shrinking in number there,,,
