The point is they're scaredy cats who jump at shadows and create deadly situations out of things that aren't. If they want me to care that they perceive things as life-or-death, they need to adjust their perception. Being scared of your shadow holding a gun and pumping a house full of rounds isn't something I'm going to think is reasonable, even if you were really scared. Soldiers in literal warzones facing trained adversaries trying to murder them aren't as jumpy as cops in a suburban neighborhood dealing with normal people. Cops need better trigger discipline.
