This doesn't make any sense. Obviously this person was a trained killer. I think the whole rifle in the woods thing is a prop. It's kind of like the passport they found untouched after nine eleven. I believe it's a distraction to make us think along the line they wanted, or to make us look in the wrong place. A kind of smoke and mirrors or a slight of hand.
It's almost like somebody's making war against us, by deception.
That's the dumbest thing I ever heard. No way! That rifle is too darn long, and it did not look like a rifle that was in the gutter. You can see a picture of him in the stairwell and there is no way that rifle was down the back of his leg and inside the backpack. You can see something going into the gutter, but it's inconclusive that it was a rifle. What ever it was, it was NOT 48 inches long.
