You're on the mark more than you know.

After his death, Capone's mob syndicate branched into California and took over the state government. The people putting Japanese-Americans into concentration camps? Yeah that was them. Public sentiment was majority against it, but they stole everything the Japanese people had and redistributed it to their friends later.

Who was in charge of that distribution? Judge David Bazelon, who invented the insanity plea... Well, this was before he was a judge, while he was just a bureaucrat for the mafia. Bazelon put a lot of effort in keeping criminals out of prison. Nobody is looking at the mob when they are looking over their shoulder on their way home, for fear of violence.

The four crime families of California, Newsom Getty Pelosi and Brown, draw their family wealth from their mafia history. They continue to participate in this mafia today.

They have something else in common too, easily discovered through wikipedia. Now Hollywood gives all the credit for mafia culture to Italians, but that's only half the story. The other half of the story is that the same mafia runs Hollywood, and they're scapegoating their former Italian allies.
