Text message autocorrect may not often lead to more than mildly comical mishaps, but today one instance of an unintended correction spread fears about a possible gunman and led to the lockdown of two Georgia schools, Gainesville Times reports. Police say that the text message, which was sent to the wrong phone number, was supposed to say "gunna be at west hall today" but was instead changed to "gunman be at west hall today." The recipient then passed on the message to the police, who coordinated a lockdown at West Hall middle and high schools. The lockdown was later cancelled after authorities traced the message to a student and discovered that there was no actual threat. We're not sure which platform performed the correction, but mobile users might want to make sure their machines don't have the final word on any text.
