Is it a good idea to plant a hidden camera in my fag’s place to see if he’s fucking other men?

Thank you for writing, Sir!

No, I don’t think that would be a good idea. I’m fairly sure it breaks a law somewhere. If the faggot discovered the camera, you could find yourself in some legal jeopardy. 

My alternative advice would be this: if you can’t trust the faggot, Sir, then maybe you need to either move the faggot in with you or dismiss it.
