At any rate I expect more attempts, including after the election if he makes it that far.
That's the same profile they go with everyone. It's a broken record, and pure BS.
Have you ever been to a Trump rally?
Every conceivable situation is reviewed, with preventing a long-range sniper at the top of the list.
But, when I went to an indoor rally, I thought if someone wanted to take him out they could. The security screening seemed Mickey Mouse.
Perhaps someone from SS got on that roof and figured that a lone gunman would not have direct access to Trump on the podium.
Which brings up the question, why did the shooter go up there? How did he know that no one was going to be there? Had he planned this before?
