TIL - Laser Microphone

Honestly, I had no idea such device exists.

It turns out there are expensive as **** devices used by intelligence agencies (but can also be bought from some selected companies) that can eavedrop windows for up to 400 meters away.

Imagine to possibilities with such device, you can literally eavedrop every single person you ever dream of without zero to no risk.

That is like 1980s technology. Today the agencies could probably just tap into your cell phone/smart tv/alexa and listen through that.
