it depends what they mean, if an ex mobster leaves the crime totally and his crime group disappears with the time its business became total legit
but if his crime groups is still active not
What I meant is that, even if they become totally legitimate, the crimes they have committed before are still there and their money is still "dirty money", so allowing them into legitimate business is a shame even if they stopped committing crimes. They should do their prison time first (of course that will never happen, I was just speaking theoretically).
i read that fbi has enough info about it, at least about how russians operate in the states
I don't know, but why then there are no big Russian mafia trials in the USA since the arrest of Vyacheslav Ivankov? At least I haven't heard of any in which a big boss got a heavy sentence.
