Are the cops in the US so inadequately trained that they have no idea on how to subdue someone other than firing a weapon at them?. Or is this case an isolated incident?
It's funny, when the cop starts shouting, his voice wavers, kind of like what happens to someone who's arguing and is 'just' about to start crying..... the fact he's getting into an argument and trying so hard to assert his authority (rather than just use his training to diffuse the situation) shows that this is all about the power trip and nothing about doing his fucking job.
Cuff them up and throw them in the back of a van, don't turn it into an episode of Jerry fucking Springer. How hard can it be.
