She wasn't peacefully protesting - she was at the front breaking through the window of a barricaded door. Totally justified whether she was armed or not. A gang of intruders comes to your house, breaks down your front door. You are now barricaded in your bedroom with your family. Intruder now breaks the glass door and starts to come through, and you shoot. 100% justified.
You obviously haven’t watched the videos if you can compare it to smashing in to someone’s bedroom. Why don’t you worry more about the gang inside the chamber selling out the USA?
I see you have wholly accepted the oligarchy’s point of view on the peaceful Capitol building protest. I guess you think the usurper is the duly elected president too?
