I know you're being intentionally obtuse, as is the fashion right now, but I'm going to give a straight response to this for anyone genuinely engaging. We don't know what went through that officer's mind. If you're standing watch and someone stands next to you and clicks a photo, is there anything you can and should do? Should you, as the officer, wrestle him to the ground, knowing there's a riotous mob right behind him? But even if it's the case that the officer enthusiastically posed for the photo, it's probably best not to understand police like a monolithic entity operating perfect information, but rather as a group of heterogeneous actors working in a fog that limits their awareness. Otherwise, if you extend the "one officer did X therefore the motives of all officers are established" logic you quickly get really stupid contradictions. Over the summer, I saw several photos of officers kneeling in solidarity with BLM protesters -- I guess that means all police everywhere support the aims of the BLM movement now? Probably not, because police aren't a monolith, and subsequent police actions contradict that solidarity. Likewise, police teargassing, manhandling, and shooting these other protesters also paints a more complex landscape than "one officer took a selfie, therefore they're all collaborating."
