So I went and I watched the video on Infowars and it's inconclusive at best. It looks like it's possible that he had a baggie of something in his hands, but Alex can't prove what that is. And the bigger picture is, like I said, it doesn't matter.

Here's what I think the video shows, and I should tell you I can't prove this, but it's a possible explanation. Right before this supposed baggie of white powder appears to drop out of Floyd's hand, he's backed against the wall by police and slid down into a sitting position. He's coming down this wall, hands behind his back. You can clearly see that this wall that he's sliding down is painted white, with some of the paint missing from the side panel, clearly visible in the video shot. I think it's entirely possible that as he was being slid into a sitting position, his arms and back scraped against the wall, and what Alex is calling a bag of white powder is really just a paint chip.
