The first arrest cannot shock the world if it's utterly covered up. If no one hears about it from a trusted source, no one will be shocked - the BOOM will be a dud.
If POTUS waits too long (and, DAMN, we're getting TOO close to the end of the time window!) to DECLAS, all will be in vain. Darkness will descend and the suicides will be good people, God-fearing, peaceful, tax-paying anons.
POTUS, PLEASE don't wait too long!
