Vigilante justice can be a funny thing.  In Indonesia itis not uncommon for criminals to run to the protection of the police for just this reason.  But the downside is that it is not just criminals.  Being involved in an injury collision in Indonesia can be life threatening for the survivors, if someone feels that they were the cause of the accident.  When I was in the bus accident I described a while back, the drivers all split and hid, because they were afraid that we, the passengers, would beat them, or even kill them.  And we might have, they were so damned negligent.  

But, oddly, even with the awareness of that level of vigilante justice, Indonesians still drive like lunatics.  So the threat of vigilante justice does not appear to be a deterrent at all.  

Uh yeah, i bet the town doesnt see another rape for awhile.  What do the police do now?  Arrest 200 people?

From the BBC:

A man suspected of rape has been buried alive by villagers in the southern highlands of Bolivia.

Police had identified the 17-year-old as the possible culprit in the rape and murder of a 35-year-old woman near the municipality of Colquechaca.

The chief prosecutor says more than 200 furious local people seized Santos Ramos and buried him in the grave of his alleged victim.

He says residents blocked roads into the village to stop police arriving.

A reporter for a local radio station, who would only speak anonymously for fear of reprisals, told the media that Mr Ramos was tied up at the woman's funeral.

He said mourners threw him into the open grave alongside the woman's coffin and filled the grave with earth.

Colquechaca is a town of about 5,000 inhabitants some 207 miles ( 333 km) south-east of the Bolivian capital, La Paz.

Correspondents say lynchings sometimes happen in isolated, poorer parts of Bolivia, where police and other authorities are scarce.
