tactic. it often arises in the context of spouses. you often have tax investigations where a husband and wife, for example, both signed a tax return. both are liable for criminal violations if the tax return is intentionally false. it often works out that the husband who was often the lead financial member of the family takes a plea or cooperates in some way to avoid having a -- his wife prosecuted as well. here you have a father and son. it is well within a prosecutor's discretion to say to a father, to michael flynn senior, look, we will not prosecute your son if you cooperate, take a plea or whatever. it's definitely hard ball, but it's done with some regularity. but the point we need to make here, of course, is that we have not established that either flynn has committed any crime. so maybe nobody will be cooperating or pleading guilty to anything.
