That I don't agree with. When you're down, it's close to over. If you are knocked or thrown to the ground and someone is hitting you, you're not going to be able to calmly point your weapon and tell the attacker to stop. If I was knocked down, and could access my neck knife> I would be trying my hardest to kill my attacker. Because if you're on the ground, you can't defend yourself well and can be close to being killed.
But for that matter, you're not going to be able to easily grab your gun either, and shoot, if you were just knocked out and wake up "fighting for your life".
The whole thing seems off.
But people are going to see what they want to see. We have seen actual videos of people being shot in the back as they run away, of a kid just sitting there, being shot to death as the cops roll up, as the car is still moving, we've seen videos of cops shooting to death someone who is unarmed and on their stomachs, face down, not moving, obeying commands. And still the cops have gotten off in all those situations.
Someone here mentioned a video showing a bunch of cops screaming at a shoplifter with guns drawn and people agreed with the cop's actions.
This shows that people will take a stance and view evidence through that lens, no matter what it shows.
