I guess it could be that it’s one legitimate case of CMD, maybe a teacher who ate the forbidden tuna, and they’re just yelling OUTBREAK in their usual way. But you’re right that there’s something… interesting going on. Something they don’t want any eyes on, given the violent police response (tho I wouldn’t call that a clue because that’s par for the course)
One reason for always saying it’s CMD (besides putting the fear in people) seems to be because it’s an excuse for Zhupao to use G6 as a surveillance tool. Now that they’re framing Efua Amankwah-Crouse as Adira, maybe they think she’s at that school giving a guest lecture, so they remotely lock it down tight and then just go in and arrest her?
