TL,DR: its dressing up in black, covering your face, etc. to conceal your identity from cops. This is a brutally simplified explanation but I think its a good summary.

I thought the main lesson last year was to cover your face and not share photos of protests with people’s faces? 🤣 I guess the intent is different, right? Covering your face for anonymity vs covering your face because you intend to commit violence…? Right?

Yes, it’s a tactic thru history it’s been used as a way to put a bloc of bodies between the cops and more vulnerable people at protests and some times for planned civil disobedience actions. And then individuals sometimes use it for property destruction.
