did he have both the guns on some sort of tripod?
I don’t know.
At last count, there were 23 weapons in the room - and what I heard yesterday was that at least 12 of them had bump-stocks. I saw one or two pics of rifles with bipods.
You would think he would be smart enough to cache several rifles at each window location so as not to have to carry them back and forth...
But even if they were on a bipod or tripod setup, you still have to exert a ton of force to control it. Otherwise, it will have a mind of its own - trust me on this.
