I'd like to talk to nascarnut.
A 150 yard shot and a kill with one shot on a civilian model rifle is very impressive. Unless he's using a scope. with a scope, it's not too tough. Open sights are another story.
He's had some training, as I don't think one nutcase, can purchase an AR-15, sit in his van and pick off people at 150 yards.
I've watched snipers take a person down with one head shot at 950 yards. That is impressive. But you've also got to figure that they were using a very precise weapon, that they were very intimate with the workings, and operation. could an average joe like you pick up a Sniper rifle and drop someone at 150 yards? Yes, without even trying. Could you pick up a hunting rifle, and drop someone at 150 yards, 8 out of 10 shots? That'd be tough.
This man has not lost sense of reality. He understands his getaway plan, his surroundings, he chooses his targets and he knows when to turn tail and run. He also understnads terror. How many people were too scared to go out? Think about the statistics...5 million+ people, 9 killed. You've got pretty good odds at coming home alive.
Do I think he sick? Yes, absolutely. Do I think he'll be caught? he could get two or three more people, and fade away to obscurity, and then pop up three years from now get three more, and then fade away again.
My fear is that he's wearing a turban, and there are others out there preparing to follow his example. New York City is a prime place. Boston, Miami, Houston, LA...anyplace that has a gas station or a shopping mall close by a freeway entrance, or a major route.
The best we can do is keep our eyes open, and notice everything around us.
