In a perfect world, which we don’t have. Again, I don’t justify the shooting without all the facts, just saying you serve the paper then make the call.
There's a situation where there innocent lives at stake, that has nothing to do with it being a perfect world or not. The question is simple: do you act differently when approaching potentially innocent people and dogs or exactly the same?
Here's another situation: you are called to a bank robbery and when you arrive there is a man running from the bank. Do you draw, aim and tell him to halt? Suppose you arrive and there are 3 women and 2 men running from the bank (you have no info about the robbery). Do you do aim at the five of them?
If it is the same response no matter what the context, is that because training is only for threats, with no deviations based on observed facts and inferences?
