That makes both of them dirty. But the WH has turned others into grey hats for bigger purposes. So that may be the case here. That doesn't preclude their paying for their crimes eventually. It will likely mitigate the consequences, though. Q has been at this at least 20 years, it seems. Many infiltrators and double agents. Justice Kav, in fact.
