Record people with a good microphone as they use their cell phone / landline (or other communication apps that compress heavily), and also record what comes out at the other end, the other end being all sorts of places, including overseas.

Next up: x-ray glasses, with several modes, to turn people into the hottest or ugliest possible version that could hide under those clothes.
