Inside Story - Disaster for Indonesia

Indonesia has been hit by yet another tsunami - washing away at least 20 villages and leaving hundreds dead and many more missing. And all this despite an expensive Tsunami early-warning system. As the waves surged towards the coastline, the system failed to work and no warning was given. Indonesia's disaster response agency says the system had been vandalised and was not properly maintained. On this episode of Inside Story, we ask why the system did not work.
