On solemn occasions, individuals who know how to comport themselves remove their hats -which tends to wreck your "just being polite" narrative. I'm guessing you didn't actually view the story or you wouldn't have made that strategic blunder in your rhetoric.
Funny you should classify Ashli Babbit as having been murdered considering she disobeyed a cop's direct, lawful orders... on camera... in a high-stakes situation getting herself capped. And before you start hooting George Floyd whataboutisms, let's just crush that right now -remind me: wasn't Floyd in custody, cuffed in the back of a cruiser when Chauvin decided to drag him out, force him to the ground and suffocate him to death? And, at the time, didn't you, with no knowledge of events beyond what you'd heard from the media, blindly defend Chauvin's actions?
