As much as I'd agree with you, could we at least see if anybody has found anything that might give us a clue about who the communists are? If we're practically going to stab in the dark, we should try to be smart about it! Even a little bit of a clue would be better than choosing her simply because she's a menace.

But if there isn't any evidence to be heard, then I completely agree. If she's not one of them, we'll still all be better off without a distraction like that causing chaos. That would only benefit the communists. If she is one of them, then she could be even worse, assuming that they can control her to fit their agenda.
