 to kill the would-be assassin Thomas Crooks. And that shot came from a Secret Service counter sniper that the source says it was, he described the shot as a one in a million type of shot. The counter sniper could only see the top of the scope, his eye and forehead because the lip of the AGR building that Crooks was on was obscuring that view. We're also told a local police sniper took a single shot as well.
