I read that he was using bump stocks to achieve full auto. Bump stocks are cool but not very accurate.
He owned 3 planes.
Would he have flown into he crowd after loading up the plane with gas and whatever bomb making materials they found and killed more people?
If so, why use the guns?
He had an arsenal in the room. Weapons, bullets. In a hotel. Presumably the “NO SERVICE NEEDED” sign was out on his two doors? And he lucked up that no manager or staff members checked the room while he was gone?
