I'm not so sure. Sounds to me like she was probably on the take, and fake licenses were no doubt a lucrative source of income for her. I'd bet that there a a lot of other non-Arab folks who got their licenses through her over the course of her 9 years at the DL division.
The connection to the Arabs is certainly suggestive, though -- they could well have used her as a conduit. The timing indicates that they are busy cleaning up loose ends.
I think the FBI is probably checking her bank transactions to see who paid her.
And I think they're probably also checking into her associations with black Muslim groups. Wanna bet that Louis Farrakhan's boys are somehow involved?
This might be a good time to suggest to any other "loose ends" that they come forward NOW while they still can...
