2 people behind Charlie Kirk give hand signals

Charlie Kirk answers the gun question very defeated and those 2 people behind him? Really? This is not standard to have handlers behind you. I think they are part of the shooting team and they are clearly signaling here. This cant be just a coincidence. I think charlie ha no choice they told him to do this wear a vest. This is why you can see the bounce because he has a vest and its heavy so it bounces.
