Who taught him how to use the guns? jumping out of a fresh crashed vehicle with airbags just blown in your face and still being able to run and gun for 12 minutes outside school before entry is rather impressive with no training. He chose daniel defense 2 guns not just 1 . He crashed truck and left a gun and ammo outside. So the bastard didnt drive himself to gunstore to get the guns. probably had fbi handler drive him to gun store. The rifle and ammo left by truck were probably for another expected shooter to show.....
