Phone in the right hand, what appeared to be a police helmet in the left hand. I rewatched after your post and I didn't see anything that indicated an "reach" toward an officer's service weapon. That said, I appreciate that I watched it from a distance and that there is a remote possibility that the officer in question might have seen the movement only out of the corner of his eye and reacted accordingly.
Also, I'm not concerned about not putting the flex cuffs on the guy. The point is that if he actually presented a threat to officer safety you'd think the police would have neutralized that threat instead of stepping past him. That part doesn't wash with me.
