Alex Rozier of KING Channel 5, the NBC affiliate in Seattle, recorded this video while covering a post-inauguration protest at the University of Washington library, according to the video description. It was posted Saturday on the station’s YouTube channel, but there’s no hint that it was aired on television.

Others have apparently stolen this video and made it viral on their own YouTube channels, and you can easily see why. A lone man who wants quiet in the library stands up to a social justice mob — and wins.
