The little spy.
FBI, Chicago cops, whatevs. The role was to infiltrate, report, and disrupt. She disrupted masterfully.
That they admitted her in the first place is their main mark of incompetence. A few months in a local movement plus an impressive speaker's presence. They loved the latter: offspring of the Speakers Bureau, the agitational soul. They devalued experience, had no notion of strategy. Thus her promotion: she speaks well, she's in.
She disrupted the youth group, by favoring some while excluding others. She disrupted the national office: It's her or me! Where the right decision was to remove them both, but they were incapable individually and collectively of making right decisions.
