StanG: The army and police didn't exactly "stand by and watch". They blocked the exits from Thammasat so the students inside were sitting ducks for their "fellow Thais." The military also fired on students trying to escape by way of the river.

You talk as though the students "took the arms and went into the jungle" as if their whole goal from the outset was to join a communist resistance. In fact, the "survivors" fled into the jungle to escape the torture and murder being inflicted on their colleagues. Have you seen the photos of dead students hanging from the trees around Sanam Luang?

Are you going to answer my original questions? --
--Where is your evidence for saying "millions of Thais ... supported the establishment and even joined Krating Daeng and Nawapol" in the '70s?
and
--Where is your evidence that "public opinion" supported the '76 military/police actions?
