One tidbit I always like to bring up is that the mob - as in, the Italian Mafia - are some of the BIGGEST contributions to gun-control politician's campaigns. They WANT effective gun control.
The reason the Italians want strong gun control is simple local protectionism. Foreign firearms models must be added to a whitelist to be legal for import and sale. Getting new models added to that whitelist takes almost exactly as long as you would expect Italian bureaucracy (and usually a bit longer).
Beretta, Perazzi and Benelli pay handsomely for this service.
