Police in my country don’t carry side arms which makes it far more difficult for them to murder people.

Though, that kidnapping incident apparently involve a firearm, so the police responding were armed, and still no one died.

Also, they tend to not get startled by noises, say like acorns falling, or if they do, don’t have a gun to fire in blind panic, and when they are armed, have the discipline to not empty the magazine like Rambo
