I'm sure that United would have appreciated that kind of regulation when they had that guy drug off one of their planes.

Really? Then you could sue me for recording you committing a crime?

Ok, let's add an exception for really obvious cases. What if you are taken to trial and later found not guilty (despite my recording being used as evidence against you). Can you sue me now?

You can see how deep the rabbit hole goes. Beware unintended consequences. If you're in a public place then I have every right to record you.

I think this would have more negative effects than positive. There’s the aspect of it’s now impossible to run security cameras or film police beating people.

But what about hearing aids and vision assistance devices? Does HoloLens become impossible without consent from everyone?
