The official sniper location was a joke.

Yes, you are correct, the setup shown is for dramatic effect and not for functionality.
I'll elaborate here: first what do we see in the photo besides three fat guys: a rh-bolt action, an optic, a barrel ?? Bueller, anyone, anyone ??, top of a rifle tripod mount, and netting.... netting ?? good grief ... not to mention a screened in window, and a partially opened double pane glass window.
Hollywood has shown snipers shooting through glass and hitting their target, but I digress.
We're talking precision here. If the operator in this photo had to make a life or death shot through the screen and double pane glass from inside this room at a target, say 50m away, the bullet would deflect, how much ? tough to say, depends on calibre, bullet weight, type, etc., but enough to potentially reduce the probability of a precise point of impact such that a follow-up shot would be required ... notice again the rig is a bolt gun - so, the operator has to manually lift the bolt handle, slide it back, where hopefully the spent casing ejects successfully, doesn't jam, nor cause the subsequent cartridge to mis-feed, then slide the action forward, push the bolt handle down, reacquire the target if necessary, and make adjustments for windage, followup, what-not. In other words, it's a slow process - because it's all about precision. He may as well open the window and yell out to his target to please hold still for a few seconds. The entire point of sniping is shot placement and minimizing followup shots, whether in competitive shooting or dot mil / gov't, especially in a life and death situation. Btw, netting has a purpose, but not as shown, likely was put on there to hide the rifle make, model, optic, etc.
A bit long winded, sorry, cheers, life
