As a Bangkok resident for over 25 years, I saw worse violence there than I have seen in Pattaya.
Saw a student get stabbed outside Pantip Plaza, and a Yaba'd up fruit vendor nutcase go on a stabbing rampage along Suk Soi 22. Just off the top of my head.
Since I moved to Pattaya, I haven't seen much. Loads of road accidents, a couple of resultant fatalities, but tame in comparison.
