For a state this seems somewhat inevitable, however pretty much all state entities have a duty to use as little violence as possible to get the job done. See European human rights act, Geneva convention etc. At the end of the day - Violet Gibson wasn’t an employee or representative of any government. She was just someone with mental health issues and a revolver. Again we come back to Thomas Mair, if your principle is that political violence is fine (again - that’s facism), then the only thing you should find objectionable about him is his politics. He was, after all, following your rules. Personally I try to follow the “do unto others...” golden rule. “Kill all others” seems to be the guiding principle of too many people.
