These are good questions, it's just my go-to line of thinking when I see surreptitious recording devices. Is this legal and is there liability? Recording audio without two-party consent in my state is illegal and only just recently were there any court cases where recording police officers without their knowledge wasn't prosecuted as wiretapping.
