You miss the point. It's not about the actions per se. It's the Thai response to the actions. For the nationalities you mentioned, similar incidents resulted in severe repercussions (see Swiss doctor kicker, New Zealand cop beaters, and the German biker gang member a while back). Why are Russians getting a pass for what appears to be worse behavior (kicking a pregnant shop owner inside her own establishment, killing an American motorcyclist and his girlfriend) and the result is meaningless punishments or none at all?
