i think this is the same news of the Eng man killed in Krabi. Actully you can get away with self deffance even a farang can. There was a english guy (once more) that stabbed and killed both the lover and the wife in bed, were he found them. After 2 years of trial he was free on the "anger rage something something law" But his is only if you are maried and you find them "doing it" and of course some money have to be transfered to make every body happy. But he got free and even his visa back. This thai guy was divorced and planned the hole thing thats a diffrent matter.
I think Thailand have a bigger crime rate then OUR country. If you read the Thai magazines there is so much stupid killing the normal TAT tourist will never come to Thailand if he knew
