I think there is more to what we think we've got - This is a comment regarding the video (link below) which makes this look like much more than a brainwashed 22 year old. Please take a look - thanks.

"I totally agree that those two men standing next to Charlie Kirk were there as spotters, one seems to have a cell phone holding it up but it's not a cell phone. What he was holding was a device that gives windspeed and elevation on a target. When he looked at it, it gave him the windspeed at that time, touching his hat on the right and right ear, he was giving signal to the shooter that he needed to adjust his point of aim to the right. The other guy was the one who gave the shooter a signal that the target was not in place,, but the shooter was set, as Charlie Kirk sat back up with the microphone the shot was taken. I might add the guy in the white hat pointed at Charlie Kirk three times, which means to the shooter to take the shoot on 3, however Charlie Kirk did lean forward to pick up the microphone and that's why the guy in black shirt gave the signal to wait, as your target is not set, but the shooter had his windspeed and elevation. The shot actually was supposed to be a head shot, as you have a line of sight and point of aim, both are critical to your target. If you pull back on the trigger the round will not follow your point of aim, it will go to the right, depending on if you are a right handed firer or left handed. The impact of the round will also strike lower which means the shooter's point of aim was not center mass, as it was to the right and lower of the shooter's planned target. This is what I taught in the Army during basic training as a Drill Sergeant. I've seen this so many times while being on the rifle range, I've retired after 26 years in 2012, basic rifleman qualification (BRM) week is where soldiers earn their qualification badges. It takes weeks and weeks to prepare them to properly handle a rifle. Besides the information on qualifying in basic training, as this recent shooting was preplanned!" and "One ex military guy on instagram said this is what they did: "it was two men, not one. Tap hat=eye on target. Touch ear=listen (wait for signal) second operative= tap arm and cross arm= take shot. They needed to do this to get a clear line of vision when he was steady. You’ll notice they did it when he was preparing to lift his mic again to talk. Once he was up right with the mic, they signaled to take the shot. This kept non-target individuals safe and out of line of fire. This was orchestrated and not random."
