Looking back at history, there were enough account from the Dutch colony era, where the imperialist got used to see the native Indonesians doing the amok. If somebody got caught of stealing or involved in social distruption, then he is in a great risk, great danger. Even so, the act of amok actually wasn't only originated in Malay culture. It's no secret this also happened in many part of the worlds including in Europe.
Back to the man who's begging for his life, he was accused of stealing a bird. Indeed, a bird. He ran into trouble when he and his friend failed attempt came into light by the resident of (how unlucky he was) an Indonesian Armies residential complex. This is smelled not like a good place to steal. He fell from his motorcycle and got punches galore by a horde of amok's fans. His friend was lucky enough to escape the crowd.
The times when we have to deal with our own anger, whatever the causes, we often show our most honest but barbaric features. While the unlucky guy laid helpless, some people still manage to kick him hard. I also saw a muscular man stomped him on the face which likely broke his jaw. We did try to stop, but this step often as dilemmatic as we were hushed. There's always risk of those violent behavior would turn towards us in no time.
A sad, tragic, embarassing, but true post for a weekend.
