Some of you are calling this a pro hit?
This has all the hallmarks of a low tech and amateur hour hit.
A few things, 1) no sniper of any training would have set up on that roof where he was easily seen. 2) The distance is a chip shot. With only an hour of training at a range, a 12 year old girl could make that shot with a a scoped hunting rifle. 3) His get away plan was to jump down from a 20 foot roof? He sprained and possibly broke his ankle jumping down.
This was no pro hitter. This was a mentally deficient person with an axe to grind.
