It was early June when terrorists in a rental van with 12-inch ceramic knives strapped to their wrists ran down pedestrians on London Bridge, ditched the vehicle, and then began stabbing patrons at the Borough Market.

That attack made headlines around the world, but it certainly wasn’t the only stabbing attack in London this year, and Mayor Sadiq Khan this week called for Google and YouTube to crack down on videos that encourage gang violence and knife crime.

Speaking of YouTube, the mayor appeared in a YouTube video to call for YouTube to remove videos that glorify gang violence and knife crime.
