 that a local law enforcement officer was told that there's potentially a guy with a rifle up there. A local law enforcement officer, by the way, assigned a traffic detail not to guard the president. And there was no ladder or anything to get up on this roof. So he jumps on the shoulders of another police officer, is able to claw his way up there, look at the shooter. When the shooter turns toward him, he has to duck back down. And he falls before he can engage the shooter because he's standing on his shoulders.
