The Sons of David are a notoriously violent gang in Gotham made up of mostly Jewish members along with some Italian members. They became famous for the vicious murder of gamblers and gangsters who dared to cross them. Many times, the deaths of these enemies were from being tortured to death, rather than quick clean deaths due to shootings or stabbings.

Stimulated by the economic opportunities of the roaring twenties and later, prohibition, The Sons of David were controlling a wide range of criminal enterprises, including bootlegging, loansharking, gambling, and bookmaking. For a street-level gang, they were smaller but more organized than others gangs which added to their reputation.

One crew in the Sons of David call themselves Murder & Associates, as if they were a mock law firm. This particular crew is notorious for putting out extremely messy and violent hits. Their strength and precision rivals that of the now defunct Victorian Legion which leads many in the underworld to believe that the “law firm” of [[Murder & Associates] is made up of one or more “masks” as well.
