The army commander Gen Sonthi Boonyarataglin who staged the coup d'etat is a
muslim.

Muslim terrorists in southern Thailand have killed more than a thousand of
people within 2 years.

There were bombs in southern (Muslim) Thailand a few days before the coup.
Police investigating reported that the military knew something about them.
There is a conspiracy of an inside job.

Nevertheless, most people believed that it was ousted PM Taksin's problem.
