As another Portlander, disagree with exceptions: surveillance footage made it harder to identify people from top down angles, and it meant that a lot of people had their charges dismissed because of that. (I will need to look it up.) The bigger risk to a protest movement, I would argue, is an opposing agent provocateurs trying to get people doxxed. That risk to more people outweighs getting minority of provocateurs shut down.

(On the other hand, you’re also right that agent provocateurs are old COINTELPRO-era tactics used by the state and right wingers against protest movements.)

When it comes to tactics to keep yourself safe when protesting, there aren’t ultimately too many hard beliefs to be had, especially when the right are perfectly happy to collaborate with the state.
