[Natural Law]

"It is an odd thing to note, but one cannot really think of an Anglican crime family, a Methodist gang, or a bunch of Presbyterian mobsters."

You seem to have overlooked the Klu Klux Klan. Not too many Catholics or Jews amongst their ranks but they were definitely an organized crime gang.

Peace and Blessings.

There was a chapter of the Ku Klux Klan in the Borough of Queens, New York comprised entirely of Irish-American Catholics in the 1980’s, Natural Law.

Thought you might find that an interesting historical fact.

Oh, and in case anyone was wondering where it was located: Far Rockaway, Queens, New York.

It apparently existed in the seventies as well.
