I would disagree. I think no one deserves to be executed. The description of climbing through a window does not sound like she was an immediate threat to life. It should have been possible to subdue her using non lethal force. I do note the responsible officer has been suspended.
I understand the 'emotional' issue, the violation some US citizens feel. But this was a few protesters who broke into a public building. This happens all the time. They did not even organise a sit in! They did not line people up against the wall and shoot them; that is what happens in real coups.
Shooting demonstrators in the streets is what happens in third world countries, the outcome of the policing here was good one person shot is one too many. I am not sure what happened to the police officer who died, all that is said it was injuries occurring during the protest, this might mean he fell down stairs. Perhaps someone here knows the nature of his injuries?
That does not mean I support Trump or these right wing nut cases, I would politically be a Saunders supporter. But even right wing nut cases should not be shot down. Police violence does not become right when it is against your political opponents.
