Yes and when I slo-mo-ed the video again it is definitely the reflection. However, he’s also definitely reaching back and pulling something out, most likely his keys. Not a good thing to do when gun-pointing cops are yelling at you to stop.
I believe he was hitching up his shorts.
But still, it could easily appear that he was possibly reaching for something in his waistband. Yep.
There was a movie a couple of years ago called The Hate U Give. It was about cops shooting an unarmed black kid. In the trailer, they are yelling at him to put his hands on the roof of the car. Instead, he winks at his girlfriend and reaches into the car for a hairbrush. They light him up.
The moral for the filmmakers: “Cops are killing unarmed blacks!” The moral for everyone else: when agitated cops tell you to show your hands, put your hands on the roof, drop what’s in your hands, etc., you better do it instead of being a smartass.
