Are you really suggesting that the USPS is opening all letters sent through them, scanning their contents and passing it all on to law enforcement? It&#x27;s a serious allegation without any proof.<p>If I recall correctly, they are actually scanning the outside of the letter which gets you senders, recipients, sending time (the metadata, so to speak.) Which isn&#x27;t very nice but also not as brazen as opening and resealing letters KGB-style.
