I was wondering if there was another one besides McMaster/s.
Don't recall one from Q, however considering I doubt it would be the only one.
Don't want to disagree with Cboldt, but part of the pressure in the mob, was that if you got outta line, your family was fair game. Do your time shut up and they are taken care of.
In the DS I would think that aside from the handlers, puppet masters and true believers there exists a workerbee analogue. They get a little grease, but are principally with the DS for the money. These may not be susceptible to blackmail pressure if their activities are benign. But they may have families who are important to them, since honor and integrity aren't.
