Still asking myself who benefits from these hoax B's and/or the motive/s. The envelopes were designed to be suspicious and intercepted. The devices are clearly a cartoon version of the real thing. 1/ scare the receiver and lots of other folks ? 2/ dominate the news cycle for a week ? 3/ blame those dangerous Rebub's ? 4/ use this event to drive the political war back to some bit of civility ? 5/ continue to send these things almost daily to spook people/voters ?
