 The Secret Service on the ground when the president got shot, I thought performed well and were all over the president, but the fact that that security perimeter didn't keep that guy out is unthinkable. The guys around the president were amazing, and they deserve to be praised, but we're learning a lot more. This guy they knew had a range finder, which is something you might use in golf to check out where the pin is, and it will tell you the exact yardage.
