The funny part is that so many people always point to pattaya and Phuket BUT
I live 5 years in Pattaya I never HAD any problem what I not can say from Bangkok
People in Bangkok are a lot more aggressive than the Thai in pattaya or Phuket if I can go back to pattaya next week, I go today. I found it also strange if I look to Thai visa (daily) that I read complete different stories that what the most people write here.
It seems like that all the people here are very lucky or maybe live too long here in Thailand and start to find everything normal, I'm the last to say that Thailand is the most dangerous country in the world but I'm also the last that gone say is saver than European capital cities.
And yes I'm agree places like Udon Thani are saver than BKK, but maybe the problem of save or not save depends on how the police react to problems and till what I have seen the do nothing and I know what I'm talking about because I work 2 years for them
