That said he was sloppy in unnecessarily muzzle sweeping the entire store after he entered. Obviously he was under duress, but he could have done better on that. As has been said, his marksmanship technique wasn't ideal either, but 5 hits in dynamic situation like that isn't bad.[/quote]
He did great. He GOTX and moved to cover while shooting.
The appropriate technique when moving to the weak side is to go one handed. You can move faster and you will be more accurate because your pistol is not coupled to your upper body movement.

He had his finger off the trigger when he came inside. That's all the safety you need.
