While there are unsolved deaths of tourists all over Thailand, Koh Tao definitely has its fair share. Lackadaisical policing with an agenda and/or something else? There is for sure a bad element there (way in excess of the norm) that needs to be expunged. Regardless of this poor lad’s death, it must be doing more harm to Thailand in keeping the status quo than making changes? I guess people will continue to go, however.
