I also made a MaybeCam (ProbablyCam) rig for my wife, for crime
prevention and personal safety:
Q. Is that a camera you're wearing?
A. It could be. I do not know, sir. I've answered your question, I do not know!
Q. Is there anyone who might know [if what you're wearing is a camera]?
A. You can go down there [to EXISTech's Corporate Headquarters] as far as you can go, and talk to Security.
Q. So it [what you're wearing] has something to do with security?
A. You're trying to put words in my mouth.
