I remember that the Mob was after “Son of Sam” because he was hurting business.
Petty crime is rare in mafia strongholds (like the Vegas strip) because dangerous streets are bad for business.
Similarly, during the Cold War, a lot of mafiosi supported conservative politicians (in spite of the politician's tougher "law and order" rhetoric) because Communism would have been even worse for business than a few token crackdowns by the FBI.
The spice must flow. They intervened against the Reds in the Spanish Civil War too.

Sounds like the plot for the movie M with Peter Lorie.
