Anyone who's lived or been around the block for any period of time in LOF (Land of Frowns) knows the deal here.

One / a group of Somchais hit on Farang girl

Farang guy defends girl

Group of Somchais get tooled up

Somchais follow girl and guy

Somchais rape girl

Somchais smash both the Brits to death.

BIB display gross incompetence/xenophobia from the beginning of the investigation, allowing the Somchais to escape from the island.

Hardly rocket science is it?
