In what may be a world first, the FBI has forced a suspect to unlock his iPhone X using Apple's Face ID feature. Agents in Columbus, Ohio entered the home of 28-year-old Grant Michalski, who was suspected of child abuse, according to court documents spotted by Forbes. With a search warrant in hand, they forced him to put his face on front of the device to unlock it. They were then able to freely search for his photos, chats and any other potential evidence. The FBI started investigating Michalski after discovering his ad on Craigslist titled "taboo."
