No one will ever call to tell you such a thing.
A cop would show up with a warrant and handcuffs instead.:D
I occasionally get an email that says they hacked my camera and microphone when I was satisfying myself, and if I don't send them some amount of Bitcoin to the listed account they are going to mail all my contacts the video.:D
The stupid part is that I don't have a camera or microphone either one on my computer.
Dumbasses, nice try though.
