There is one thing that tells you that most of these shootings are deep state phsyops. They always use handguns and assault riffles.

if it were real someone would use a short barreled drum fed semi auto shotgun with 4 to 12 shot, the shock and awe would be massive, huge blood bath, few would survive in close quarters there would be parts of people all over the place. Why do you think they used shotguns in trench warfare in WW1 and WW2? you cant escape the spread. Do you know what happens when you shoot someone at 5 yards with 12 shot? It takes limbs off or puts a huge hole in a torso.
