I believe you are the one doing the spinning here.
You’ve watched the video multiple times, but have you watched and studied it in slow-motion?
In normal time, it is hard to tell what is going on.
In slow-motion, a lot more can be seen and studied.
Now tell me, will the FBI be studying the video in slow-motion, or just in real time?
I honestly don't see why the one cop decided that hand-to-hand combat was the best solution to the situation. The guy gets pinned by two cops, which immediately subjects both of them to having their own guns grabbed by the arrestee.
I don't see the propriety of the situation that was created by the one cop deciding that a Roman Reigns spear move was the right thing to do.
If someone is supposedly armed, don't you keep a safe distance?
And then, if they start reach for a gun you can blow them away before their hand is even finished reaching into their pocket.
It looks like bad procedure to me.
