One of the tricks our politicians use is to create DRAFT EMAILS and not send them.
Then, you get a new phone with the same number and give your old one to your ‘aides’ or anyone else you want to communicate with in secret. They can then go into your email and SEE that DRAFT. Once they have read it, they can then delete it.
NEAT TRICK, and in the political community, it is a well known and highly practiced trick.
I assume it’s similar to the Petraeus drop box without traces on the internet.
Interesting.
