I mean, you know how everyone carries a phone these days? If you use your voice, it could be potentially recorded.
So… we could just use sign language. Teach everyone sign language, use that whenever you wanna say something anti-government.
Its much easier to cover up cameras (or move out of sight) than to cover up microphones. And its unlikely people would want to leave their expensive phone in another room out of sight, so teaching everyone sign language seems like a straight-forward option.
Also, bonus: its very helpful for people with hearing problems if everyone knew sign language.
Laser microphones can record audio via line-of-sight at a close to unlimited range.
Oh yea, I learned about those when I was a teen. Since then, I kinda feel like NSA was always watching me, just imagining some dude in a suit somewhere on a rooftop aiming the laser at the window just to listen in, even tho I did nothing wrong.
Now the dudes in suits are in your pocket (phone microphone) lol.
