The training, what little there is, is the problem in this case unfortunately. All the killology and us vs them horseshit they tell cops leads to precisely this type of situation. Proper training means that is indeed more than enough time to check down an ROE before using lethal force, but when you have a hammer and no one punishes you for hitting the wrong nail…every kid looks like a nail if they’re they wrong socioeconomic type or color and you’re constantly in “fear for your life.”
