I go with the assumption that every state agency around the globe is reading as I type right now. I just care less than less.
Back in the day a group of Russians visited Moscow and all shared the same room in the hotel. They were soon drinking, talking, telling political jokes, laughing, and generally making a lot of noise.
One of them eventually wanted to sleep, so he asked the others to be quiet, but they kept going.
Finally he got an idea. He went out of the room and told the attendant to bring him a tea, but wait for a couple of minutes with it.
Then after returning he said to his friends: “Shut up, this room is under surveillance.”
They laughed.
Then he lifted a corner of the carpet and said: “Bring me a cup of tea, please.”
Suddenly, the attendant shows with the tea.
They were all are stunned and shut up instantly.
In the morning, the guy woke up to an empty room.
He asks the attendant: “What happened to all my comrades?”
“Oh, the NKVD took them all away! And, by the way, comrade Major really enjoyed your carpet trick!”
