I think what he meant was that in order to shoot 5 shots at such a rapid pace you need to be an exceptionally good shooter. Crooks apparently had some training in shooting but was he able to shoot as fast as e.g. Miculek? Maybe this is a moot point, I don't have enough expertice to determine.
I see the point now. (Duh!) The 5 alleged Crooks shots WERE fired off in less than a second. I was thinking it was longer than that. According to one of the working hypotheses so far, though, those were the shots fired by Crooks... Maybe he was just that fast, or had a rapid-fire trigger? (Here's a random guy shooting 5/second, and another guy doing 6.)
Fascinating, if true, that Rep. Pat Fallon replicated the shooting with his AR-15, firing 8 rounds from ~130 yards, and 7 out of 8 of his bullets hit the target's head.
Another reason he shot so fast was the urgency of his situation: he just pointed his rifle at a security/policeman and it was a very limited time for him to act if he was to succeed - having been discovered. So he was in a race against time.So, not only by turning his head at the right time did Trump avert his death, maybe the immaturity of the shooter sent him into a emotional state and insecurity that made him have a hissy-fit while aiming his rifle.
Maybe there's an entrance to the building on that far side where someone just had to pop downstairs let him in?
