Doesn't really matter whether it was 60 minutes or 60 seconds, they knew about Crooks and had plenty of time to neutralise him. There was someone with an exposed weapon within range of a public figure, even if security didn't want to actually kill Crooks they should have at least put a round towards him to show him that they had him covered and maybe damage him or his weapon. He definitely should never have been allowed to take the first shot.

It doesn't matter whether you think Tump is good or bad if that security sniper was ordered not to shoot after reporting an armed threat then his superiors are completely unsuited for their job. In a situation like that security shouldn't have even needed to ask for clearance, it should be automatic.
