This is a confusing article. I kinda get it but isn't it saying that our observations make the measurement and our measurements can't be taken as objective fact but it's more like how our brain interprets it? I like how it sounds but I need someone to quantify this somehow with data

I don't like "the shoot first, ask questions later" mentality. I always thought a cop should be a white knight. They need to be ready to throw down their lives to save someone. A us vs them mentality, the fact the police are people and some have families and their own wants and needs will mess with anyone's line of thinking. Police have to be ready to risk opening the door to confirm a dangerous suspect before they use force to try and save themselves.
