I don't know excrement about guns but why was the flash of the muzzle of the shooter blatantly apparent, but there essentially none from the officers gun?
Looking on a cellphone so I can't see excrement but is it because the gunman is using a (shotgun?) and the officer just has a pistol or something?
Also I understand being absolutely freaking terrified during something like this, but the mind-numbing screaming I just don't understand.
