Well, that’s one way to get attention. David Hampson has been blocking traffic in Swansea, UK, for over 11 years, and nobody knows why. He stands in the middle of a busy intersection until police arrest him, then goes to jail for months without speaking to anyone. When he gets out, he goes right back to blocking traffic again. Courts have tried everything to figure out what’s wrong with him. They know he can talk because prison guards heard him speak, but he chooses not to.
Doctors can’t help because he won’t talk to them either. Judges have ordered psychiatric reports, but Hampson refuses to cooperate. His latest arrest happened in June when he blocked traffic outside the police station. After more than a decade of this strange behavior, David Hampson remains a complete mystery that nobody can solve.
