Facebook made an “operational mistake” this week in failing to remove a page that encouraged armed Americans to take to the streets of Kenosha, Wisc., CEO Mark Zuckerberg said.

The page clearly violated Facebook’s rules against violent militias, Zuckerberg acknowledged in a video posted Friday to his Facebook profile, and that “a bunch of people” had even reported the page prior to the killing of two protesters, Joseph Rosenbaum and Anthony Huber.
