I imagine if my occupation includes carrying a gun, interacting with citizens, and a historically high rate of extrajudicial deaths amongst people I am supposed to be protecting. A publicly accessible camera would be beneficial to easing the minds of those I interact with and providing evidence for any actual instances where I felt my life was threatened.

Probably until either the nurses stop panicking in my local area or the immunocompromised people in my life die of a preventable illness.

Maybe people are setting it up at home using a numberpad? In that case it would be just running a finger down the left side.

I don’t recall the books well enough to be sure, but knowing Pratchett, there is almost certainly a direct reference to that quote in there.

“But, when I talk to people in general, most seem to not worry because they “have nothing to hide”, and most are only worried about their passwords, banking apps and not much else.”

Sounds like they have passwords and banking apps to hide, You should demand their bank account and credit card details to verify that they have made no illicit actions.

If they point out that they have no reason to trust you with that information, that’s when you point out that police, government, or corporate groups are made out of people just like yourself. They might have some codes of conduct, or a vetting process, but it just takes one person malicious or careless enough for you to be severely impacted.
