If you're breaking into a room or a building and there is someone on the other side pointing a gun at you, then you stop what you're doing and walk away.
To assume the other person will act with restraint is to demonstrate an incredible amount of confidence in the training, the intellect, and the composure of the gun-bearer; that the person will not shoot is an assumption that nobody should ever make.
It's a common theme here in the forums that if a motorist had just listened to the commands of the police officer who stopped him, he would still be alive.
The principle applies here as well. When the guy showed up with the gun drawn, it was clear he meant business, even if he may have been dumber than a bag of hammers; everyone on the viewer's side of the doors should have stopped immediately.
I get what you’re saying, and no flames from me.
Here’s another video, that shows LEOs standing in front of the same doors. Congresscritters are in the hallway on the opposite side of the door and being herded away to safety. Three minutes after the critters are escorted away, a man in a bush hat attempts to de-escallate those trying to intimidate the officers. The LEOS in front of the doors move to the right of the door, against the wall where they remain as the ‘f the police’ anarchists go back to torturing the door nearest the shooter.
With the critters long gone, and back-up onscene, exactly who was the shooter protecting ?
Ashli moves forward.
Situationally for the shooter, the door was barracaded, the guys to the left were trying to pry open a different door, LEOS remained onscene at the right, to be joined by M4 tactical guy and half a dozen of his buddies who seemed to arrive just as the shot was fired. And, there was the backup doorway the shooter was standing in. Both of Ashli’s hands were needed to hop up, so obviously unarmed. Where was the threat that called for lethal force? And if the shooter felt bodily threat, why did he only shoot to the right instead of at the doors nearer him being pryed open? Why did he not step out of the doorway to assess the situation prior to shooting?
Like I said, I get the perspective of what you’re saying, but otoh my perspective is, I can’t shoot a burgler in my own home unless he’s pretty much sitting on my bed and even then I might still be liable here in California.
