Boston arrested protester names have been released - good idea?

I would take refuge in the law. If arrests are public record, I can't see why they shouldn't be. Well, I can see some downside to the individuals, but it's not something that would bother me.

I did notice that the daughter of NYC's mayor had her name released. That might serve as some sort of unofficial precedent.

It's tied-into all AI tech and is mandatory.
If a streetcam assumes you to have been in an altercation - 50pts demerit.
Purchase a 'happy birthday' card - +50pts - ....

The normal procedure should be followed. If someone did a crime during a protest, it should be the handled the same as any other time.
