Exactly.
“Don’t do it!” Read a book? Shows they lied immediately. Wanted to hit the cop shooting lotto.
“Drop the gun!” over and over and over. That’s no quick trigger officer. They don’t have to wait for actual pointing and firing at them to shoot. Gun can go up in less than a second and he was clearly warned. Looks like a good shooting.
Under such conditions a defender (here a police officer) cannot respond in time before the gun comes up and shot goes off.
Someone is going to get shot.
