Yeah I’ve hardly got a press card so I can’t use clothing that indicates as such, though I’m not sure what issue there would be with just plain high visibility clothing. The main thing I’d want to avoid is a situation when the police tries to stop movement into a certain area, which is particularly prevalent at counter protests where you need to keep two opposing sides separated, and I’d be identified as a protester instead of a disinterested observer.

For instance in the US you have ACLU legal observers, who are able to be identified easily as separate parties to protesters (at least I hope they act impartially)

I live in the UK so perhaps it’s different where you are, but generally this kind of stuff isn’t used at the types of events I’d be interested in so I’ll be fine for that. And yes in the UK filming laws are very liberal so there’s no legal problem here.
