“BBC REPORTER: You weren't inside the event but you were just outside. Tell us what you saw.

PENNSYLVANIA MAN: So we had a party here all day and you can see behind us at the [local restaurant] here, we had a party. And we all decided, "Hey, you know, when, when we hear Trump up there, we're gonna walk up through the field, stand by the trees out there under the shade and listen to the rally."

We couldn't see him, but we could hear him. So we walked up and after probably 5 to 7 minutes of Trump speaking... we noticed the guy crawling army style, you know, bear-crawling up the roof of the building beside us, 50 feet away from us. So we're standing there and, you know, we're pointing, we're pointing at the guy crawling up the roof

BBC REPORTER: And he had a gun, right?

PENNSYLVANIA MAN: He had a rifle. We could clearly see him with a rifle. Absolutely. We're pointing at him.”

The police are down there running around on the ground. We're like, "Hey man, this guy is on the roof with a rifle!" And the police are like, huh, what, like they didn't know what was going on.

You know, we're like,"Hey, right here on the roof, we can see him from right here, we see him, he's crawling."

And the next thing, you know, I'm like, I'm thinking to myself, I'm like, "Why is Trump still speaking? Why have they not pulled him off the stage?"
