| Alissa Wright’s 13-year-old daughter arrived home from her Los Angeles school Wednesday with an announcement: Charlie Kirk was dead, and she had watched a video of it happening. Wright’s stomach dropped, she said. The 47-year-old stay-at-home mom had seen the gory video of the conservative commentator’s killing at a Utah speaking event earlier that day as it spread on TikTok and Reddit. Her daughter said that a boy in her class had sneaked around the school’s phone ban and discovered the video on TikTok. Cable news channels and mainstream media outlets aired edited videos that omitted the shooting itself, but on social platforms, uncensored videos filmed at the scene from long distance and up close quickly surfaced. Apps like YouTube, TikTok and Instagram are designed to play one video after another as people scroll, prioritizing the posts that draw the most attention. Experts said it was impossible to quantify just how many people, and how many kids, the videos ultimately reached, especially since many were taken down. “This one moved at a pace you can’t keep up with,” said Jill Murphy, chief content officer at family advocacy group Common Sense Media. |
