There's not really anything that you can categorize in good faith as "surreptitious" about it.

And likewise, the relative infrequency of surreptitious recording being useful will limit how often the devices will be used that way.

You have to show some unusual circumstance--such as one party's surreptitious alteration prior to signing--if you want to claim there was no meeting of the minds.

Outside of my tech-oriented friends, most people I've discussed surreptitious electronic government surveillance with are either unconcerned about it or actually for it.

They do --but with the camera & video equipment available today, unless they search people before they enter facilities and confiscate, it's more of a gentleperson's agreement that people will not take surreptitious photos of others' equipment.

Not at all unlikely since the FBI has been in the practice of using surreptitious entry since at least the 1970 at the behest of the NSA and the CIA in a bid to recover cryptographic keys and other information instead of having to brute force them.

The Government, operating primarily through secret informants, but also using other intrusive techniques such as wiretaps, microphone "bugs", surreptitious mail opening, and break-ins, has swept in vast amounts of information about the personal lives, views, and associations of American citizens.
