BTW 70 yds with a 9mm pistol aint impossible (on a bicycle) but it is improbable.
In a 9mm carbine, from a fixed position? its a pretty clean shot.
The absolute longest distance inside the building where the shooting took place is 60 yards. I can hit a torso sized target at 60 yards with a pistol every time. Would I rather have an AR? Yes, but the pistol was enough gun for the fight. Also, the Sheriffs dept has stated that the shooter DID NOT have body armor, so again, 9mm or .40 would have been effective.
