Leaders 'drunk on power' are world's biggest threat, says Ugandan opposition activist

Musician-turned-politician Bobi Wine was forced to flee Uganda last January after soldiers broke into his home and attacked his wife. That was after President Yoweri Museveni, the country's aging authoritarian leader, was declared the winner of a disputed election. Wine tells The World's Host Marco Werman that Museveni's powerful son is determined to crush the last vestiges of democracy in Uganda.
