That's such a crock of shit lol. Mob guys are involved in every type of crime imaginable. No crime is too big or too small. From breaking open parking meters for the change they contain to the most sophisticated internet or banking scams. And weapons trafficking is a common trade for Italian organized crime. Wake up NYMafia.
The only mafia member ever breaking parking meter open to steal dimes was Al Pacino in Donnie Brasco. These 2 guys are the sons and grandson of a deceased member, they are not members. I doubt they are even associates.
The alleged father-and-son crime duo are descendants of Joseph T. Tomasello
I doubt they even know anyone in the mob. If they do, in todays world that means they can just give up a made guy (Weather or not the made guy was involved) and get off with no time served.
