yep, you can record any conversation you're a part of by hidden device and the other party does not need to know. Except courthouses. Did this during my divorce with a family counselor as she was a man hating "cunt" and obviously playing for the other side. I can't even explain how ticked she was.. She demanded I give it to her on and on and on and on. I just smiled, pulled it out of my pocket and said NO, keep talking, what are you afraid of?. She went on and on about how it's against company policy. Does not matter, i didn't sign anything. She was FIRED UP and went bizerk. Sorry, off-topic, carry on
