I didn't know him, but as I have said in another post, I would think it was his words, and possibly his actions, rather than just beeping the Scoopy horn, that has led to this incident taking place.
I am certainly not a Thai apologist, and this is well know through my posts.
I am not victim blaming either, because the reaction by the other driver was of course excessive, with murderous intent.
I just find it difficult to believe there would have ONLY been the beeping of the motorbike horn that offended / insulted the offender. I think Neil said and / or did, more than just beep the motorbike horn.
Did he deserve to die for it, of course not.
Did you witness the incident?
