IMO the shooter did not need to strive for accuracy. If only a third of his bullets found their mark in that crowd, that’s still a lot of strikes. A panicked crowd stampede did the rest.
four rounds fully auto at 400 yards and all four hit the head?
Exactly. All you have to do is point the gun in the general direction of that crowd, and you’ll hit many people.
Tripod a must? I don’t think so. Could he have used one? Sure.
As for all the guns he lugged in, how many were long guns?
It will be interesting when the list is revealed. He could have put a number of guns into a bag, and simply moved them on a cart.
Some people request no housekeeping on a daily basis, for privacy concerns.
If asked what was so heavy, he could have stated he was getting ready for an event, and had lots of equipment.
I question his marksmanship and feel the number of hits was simply due to crowd density and the number of bullets he could fire.
With all the apparent planning and preparation the shooter did it’s not unreasonable to think that he practiced beforehand at the distance and elevation he would be firing from.
There are thousands of square miles of isolated desert nearby where he could practice in private all he wanted.
Plus, we don’t know what type of scope he had on his rifles.
From all reports he had some high end rifles so its likely that he had some high end optics too.
And as others have pointed out, shooting at a crowd of 22,000 jammed into an area the size of a football field doesn’t call for expert pinpoint marksmanship.
His case is based on the high degree of accuracy displayed at a massive distance. That’s his point. This wasn’t spray and pray.
