Viability basically means meeting the two factors that make up RICO: an ongoing pattern of racketeering in behalf of an enterprise. That's it. There's got to be continuing activity and there's got to be some semblance of an organizational framework. The only families who meet that standard, and are recognized by the feds, are the 5 NY families, New Jersey, New England, Philadelphia, Chicago, and maybe Detroit. I say maybe for Detroit because there's differing opinions among mob experts regarding Detroit and, needless to say, there hasn't been much discernible activity there in recent years.
