Does fog of war mean anything to you? Go to a crowded place where everyone is armed. Person 1 is a baddie and kills person 2. Person 3 is a Good Guy and shoots person 1. People 4, 5, and 6 are also Good Guys With Guns and didn’t directly observe the original altercation, they only observed Person 3 shooting Person 1, and assume Person 3 shot Person 2 as well. People 4, 5, and 6, open fire on Person 3. They are bad shots though and the adrenaline dump makes them miss, so People 7, 8, and 9 get shot in the crossfire. At this point it is total chaos, everyone is either shooting at everyone else (fight), running in panic (flight), getting shot in the crossfire (freeze), or just shrieking their head off at the carnage in front of them (freak). Then the police arrive and shoot the survivors.
Congratufuckinglations, we now have a bunch of bodies and dozens of traumatized people because you morons couldn’t leave your fucking guns at home and enjoy the goddamn beach.
