Prayuth has definitely noticed it and mentioned it as an action item for his post-martial law, Article 44 phase of government, so it'll get some attention. The press conference where they line up a few Rohingya fishermen and blame them for the faults of the DCA should be a hoot.
I'm mostly curious why now and why Thailand specifically, when Malaysia seems like an obvious target for scrutiny given recent events. There are a number of international political footballs in the air, from the AEC free labor reforms to Thailand floating the canal again to the US anti-trafficking push here to the pressure to return to democracy and so on. I don't doubt the validity of the findings at all, and I hope this causes the cleanup that's needed (not holding my breath). Central reforms like this, that don't involve huge contracts (i.e. military, infrastructure, etc) and aren't provincially homed, are much more feasible here, so maybe something will get done. We'll see.
