Explain to me how recording device A "when caught" (i.e., the glasses) differ from recording device B (say, a smartphone) "when caught", with respect to "plausible deniability"?
In both cases, do you not have the person responsible for making the recording (because they've been "caught" as you say), regardless of the device used to make it?
If you do, then that person has, as you say, no plausible deniability at that point, do they not?
And if you don't, then isn't the device type used to make the recording in question, irrelevant?
Because you haven't "caught" them?
Also, why do you care so much about plausible deniability as relates to a specific type of device?
Are we talking about legal accountability, or are we talking about something else entirely?
What do the glasses enable that any other video camera does not?
I suppose that someone could argue that the glasses enable covert, non-consensual recording, and that this behavior might be abused by certain individuals, and that would be a valid argument, but I don't think it could be applied to only Meta's video glasses (i.e., Meta is not the culprit) -- it would have to be applied universally to all companies present and future (including all of the ones in China) who manufacture smart glasses...
If I may suggest...
If the central issue with these smart glasses (made by whatever manufacturer, present or future!) is that they enable covert non-consensual recording, then how would it be if the manufacturers put a big, red light on the front of the glasses, that would automatically turn on when the glasses are recording...
If these glasses were created with big red recording lights that turned on once the device started recording, then that might serve as adequate notification that the counterparty is being recorded, would it not? (You'd rather someone, if they were going to use video recording glasses have them with a big bright red light, then no such light, right?)
So, to recap, I don't understand.
You're looking for a way to prosecute unethical individuals who use covert (or at least, somewhat more covert than a cell phone, let's say, at least until large swaths of society accept the existence of video recording glasses like we already do with smartphones) video recording technologies, such as those found in smartglasses?
Or is there some other issue or issues?
I don't get it; help me out!
