Is it standard practice to use deadly force based on an assumption?

[Anitius Severinus Boethius]

Yep. If I am in my house and you come in with a gun drawn, I assume that you intend to do me harm. I will use deadly force in that matter. If it later is revealed that you had a water pistol, my assumption still stands. If it is later revealed that you are 14, my assumption still stands.

If an agent has a car directed at him and the driver accelerates at them it is an assumption that the driver intends to hit the agent with the car. That assumption still is valid even if it is later determined that a 14 year old was behind the wheel. Remember, a car doesn't turn to nerf if a 14 year old is driving it, it can still maim and kill as if an older driver is behind the wheel.
