Complete ineptitude or inside job.
It's a flat roof. Based on my Google Map Image skills, I show the shot as less than 400'
That is well within what the secret service would consider a threat distance. With a rifle and scope, that isn't an overly difficult shot. Especially from an elevated position, lying prone and aiming at a stationary target.
The media is saying it was an "AR style" rifle - which for those dipshits just means it was black. An AR isn't really a great choice for a long range snipe unless it is built specifically for that purpose. It will be interesting if we get any details on the weapon.
