Murder Inc was a myth. It was a loose affiliation of Jewish gangs that was misinterpreted (based on a pre-Valachi understanding of LCN) to be an enforcement wing for the Commission, and this idea has been repeated to the point where it is accepted as truth. The killings attributed to 'Murder Inc' were carried out by those Jewish gangs, sometimes with the approval of Albert Anastasia (to ensure they weren't killing anyone they shouldn't). Executions ordered by Anastasia are generally also attributed to 'Murder Inc', but the idea of Murder Inc as a clearly defined entity carrying out contracts nationwide for LCN is a myth.

Murder inc. a myth? I’m sorry but t that’s gotta be an attempt at humor. No way it can be a serious comment
