Donald Trump (All General Trump Conversations Here)
I'm not sure. As a rule, I'm for minimal force. With proper training, there should be a way to prevent a threat without resorting to a lethal shot. And this was clearly that. What might mitigate the situation in this context would be:
a) An angry, potentially armed, crowd shouting that they wanted to murder the VP.
b) If there was a warning.
I mean, suppose he let the woman climb through the door and she was armed and intent on killing lawmakers? His career would be over if he wasn't already dead. There has to be a final line of defence and it would be totally justified to presume these people (as a group) to be terrorists considering what they were openly claiming they were going to do.
Again though, not enough information just from the video for me. (And I might add, I consider the woman mostly to be a victim of Trump and his cronies and it's a tragedy she was killed).
