I might add that masking up is a good idea even if you plan on doing nothing but observing. Sometimes rightwing media personalities will photograph unmasked people at protests in an attempt to send online harassment their way regardless of whether they’ve done anything wrong. Additionally, there have been instances where innocent individuals have been charged with actions that other people in the crowd did, so even if you plan on being good, you could still get in trouble for the actions of others. A mask would add another layer of protection from identification and hopefully prevent you from getting wrongfully charged. I expect this administration to be particularly vindictive against protesters.
