I think this more has to do with eliminating the possibility of that frightening prospect of... AN INTERNATIONAL INCIDENT. When a foreigner get's into trouble in Indonesia, it creates AN INTERNATIONAL INCIDENT. Nothing is so scary to Indonesian politicians as AN INTERNATIONAL INCIDENT.
So I think this decision just reflects the fragility of Indonesian politics, which can easily be set into turmoil and overwork by AN INTERNATIONAL INCIDENT.
