The “Red Boots” guy.
In one of the photos that includes red boots, there is a fat guy wearing a MC club vest, fixed blade knife (I’d guess 6 or 7 inch blade) prominently visible hanging from his belt. He’s talking to a fat cop who is holding an assault rifle, and red boots is holding an assault rifle. The scene does not appear to be one where red boots and the fat cop are demanding submission of the fat biker.
