Anyone else seen this 2008 movie "Traitor"? About 80% of the way through there is a scene where Samir (Don Cheadle) tells Omar he has a better idea for communicating with their terrorist cells than via emails, which can be intercepted.
Get this: His idea is to create a bunch of email accounts assigned to each cell, type each terrorist's instructions in an email but do not send, save as a draft. Then send each terrorist their account login, after which they would access their assigned account, read the DRAFT email containing their instructions, then delete the draft. Sounds familiar?
Probably ancient news, but in light of Biden getting the idea to use the Logan Act to go after General Flynn from an episode of West Wing, it jumped out at me.
