“But cops have firearms training!
It was like watching one of the Police Academy movies. Shoots being fired fast and everything being hit but the suspect whose only saving grace was that he was as shitty as the officer.
Two and a half mag dumps to bring the guy down and the officer is so rattled that he did not see his weapon was solidly slide back.
I did find the photo of the firearms instructor for Houston PD.



As soon as the gun came out the officer should have fired. Instead he retreats telling him to drop the bag while the perp points a gun at him.
There is a certain "period of mild stress" factor involved here. I know a few cops, not many but most of them will admit the uniform and the badge are generally enough to get compliance. In reality, very few cops will actually encounter this situation in the wild.

Does not mean they should not train for it. It is not an excuse, but most humans will not do the right thing when actually confronted with a life or death situation.

Freezing and fumbling about is to be expected. I would guess this particular officer has never had to draw their weapon in a real life situation before, and if they did, it was likely with significant backup, or as backup.
