 That was something that was unusual because usually if you bring binoculars, you would just bring binoculars, not a range finder, not criminal, but they thought it was a little suspicious. And then about 40 minutes before the shooting, he got back on the Secret Service radar. There's a photograph showing the sniper appearing to crawl on the ground while scouring the area, and that was circulated to law enforcement as a suspicious sighting at 530. That's the first photo that was making the rounds on Saturday.
