I agree, of course. And is it reasonable to say "they were reaching for my gun" or "they were moving toward me" or "I felt threatened"? These all seem like well

I agree, of course. And is it reasonable to say "they were reaching for my gun" or "they were moving toward me" or "I felt threatened"? These all seem like well-practiced platitudes. But having said that, I'm not sure that I would be much different if I were in their shoes. I travel - so I've spent time in bad parts of Jersey and Chicago. I would probably be doing the same thing to justify whatever I was doing to keep myself safe - including categorizing everybody as "the enemy". We need to find and address root causes - patching symptoms won't work.
