I put this behind a spoiler because it's graphic. I have no idea if it's real or not but looks like it is. Things like this get out and then are sanitized immediately. My wife saw this last night.
Looks like they wounded him in the center of his skull blowing his teeth out which is probably what they train for - to instantly neutralize a target. The idea that a wounded sniper might continue shooting is why they do that. 130-150 yards should not present any difficulty.
The effective range the rifle the sniper used is generally about 400 yards if it's a standard 5.56 NATO. The accurized rifle the counter-sniper rifle could probably easily double that.
There are reports of a local deputy heeding the warnings about a man with a rifle who actually went up on that roof with a ladder and if true maybe it caused him to rush his shots. Hard to say what's true and what isn't at this point but that doesn't sound outrageous to me. We'll see.
