Have some thought on the shooter.
He does not seem to be a pro.
First of all, no pro would ever go that close to shoot someone, 200 yards open line of sight? If he is a pro, he would know this is the place to be if I am doing security. Either he is also thinking of overpowering anyone, which is going to be hard, especially before the kill shot. Or he didn't think of that.
Secondly, no one I know is a pro who would aim for the neck. Whether you are doing a trick shot or you mistakenly hit the neck, most snipers are taught to get either a headshot or a heartshot, depending on whether or not the target was wearing body armor. SF snipers were taught to aim at the shoulder or straight toward Subclavian Artery, because you need to move your hand, so there is no way you can cover your shoulder, and if you are using a high-power rifle, you can have a clean shot through the Subclavian Artery from the shoulder. Your target will bleed to death in seconds.
On the other hand, funny enough. 200 yards is usually the first ballistic drop notch at most hunting scopes, so if the shooter is aiming squarely on Kirk's head, it will hit his neck because of the ballistic drop
I will say he had a certain degree of planning, which included how to conceal the weapon before the shooting, probably location scouting (He didn't end up on that roof with clean LOS by accident), but I doubt he had planned his escape. Either that or he is a very, VERY well-trained operator, and he simply leaves a decoy clue for you to find.
