Vernon Unsworth, the caver accused by Elon Musk of being a pedophile, filed a defamation lawsuit against the Tesla CEO. Unsworth is an experienced spelunker who helped save 12 boys and their soccer coach from a flooded cave in Thailand in July. Musk grew angry with Unsworth after the caver criticized Musk’s attempts to help with the Thai cave rescue effort by building a miniature submarine. On Twitter, Musk made the unfounded claim that he was a “pedo” or pedophile. Musk doubled down on his claim in other tweets before deleting them.
