I already noted it in the answer. If a person feels at risk, or even if they're on vacation, they have a right to record something/everything and someone/everyone around them in public, just as they could with a phone.

Do you think you will know if someone has their phone in their pocket or in a holster, and is turned on and recording? You will never know.

There are dozens if not hundreds of cameras pointed at the street that record people every time they go out in public in any urban setting.

If someone is recording you on video with a smartphone, you are generally aware of it, because it has to be pointed at you. Sure, you have a right to record people in public, there is no reasonable expectation of privacy in a public place, but I would quite like to know if you are recording me. I'm also not terribly worried about people recording me having sex or being naked in public without my knowledge...

> they have a right to record something/everything and someone/everyone around them in public

Subject to local law. It's an offence to make indecent images of children, for example.

However, it is absolutely not the case that Meta has a right to that data, as a data controller under GDPR.

> feels at risk

This is a red flag phrase: it's a justification that people whip out for all sorts of unjustified things up to and including murder.

> Do you think you will know if someone has their phone in their pocket or in a holster, and is turned on and recording? You will never know.

At least this says something about the intention. Someone who films with a hidden phone implicitly shows that they intentionally hid this from the people being filmed.

Filming with glasses is hidden by design. It gives plausible deniability to the person filming, so they can film covertly but pretend they weren't hiding anything.

In most cases this doesn't make a difference but there are some cases where the premeditation can make it worse for the person doing the "abusive" filming.

>> even if they're on vacation, they have a right to record something/everything and someone/everyone around them in public

Big assumption here that the place you're on vacation doesn't have different laws. You may have absolutely no right to record "everything and everyone" around you.
