While covering the report of an active shooter at YouTube, MSNBC's Nicolle Wallace got skittish.

Someone on set opened a can of soda, and Wallace mistook the sound for gunshots.

Wallace was in the midst of tying the story of a shooter at YouTube's San Bruno's office back to her time in the Bush Administration during 9/11. Wallace was lamenting how difficult it is to enact gun control legislation after mass shootings and said people fall back to their "tribes," much as they did after 9/11.

"Steve Schmidt, I always go back to the horror of 9/11 and the complete reliance, you know, we're in our tribes, we're in our corners most of our lives," Wallace was saying when someone, apparently in the control room, opened a can of soda and inadvertently left an audio feed on.

"I think we just heard some gunshots. Should we listen to that for a second, control room? Not gunshots? Okay. They'll tell us if there's something we need to dip in and listen to."

Check out the clip above to watch the strange moment.
