Nasty people jump straight to Blaming the foreigner "He must be drunk"! Try looking at the photo. Barrier, that is a little exaggerated, look at it, it's almost knee hight at the large step. Path is also unsafe with several area's one could trip resulting in one tripping. The other fact is its outside a hospital. Maybe he was going to the hospital, tripped and died. This should never have happened, the drain should have been covered, no massive steps and flat smooth sidewalks. Thailand inferstructuer is 3rd world at best except for sky train and MRT. Let us not forget the possibility of being nocked in by a motorbike driving on the path. Lots of possibilities. Stop Blaming foreigners.
