You, clearly, did invent your "statistic". You should have re-read your comment that I responded to and properly read the survey that you linked, they represent two completely different scenarios. This is what you claimed...
" The ratio of murders, fights, car crashes, general illegal activities caused by visitors to Thailand vs visitors to say Singapore, Malaysia etc per 100,000 is astronomical"!
The survey did not assess the illegal activities caused by visitors to Thailand (or any other countries), this is what the survey actually covered...
"1. This metric reflects the overall level of crime in each city.
2. This metric reflects the risk from crime, violence, terrorist threats, natural disasters and economic vulnerabilities.
3. This metric reflects the level and quality of healthcare services and infrastructure in a city.
4. This metric reflects the availability and quality of city infrastructure and its vulnerability to man-made and natural disasters.
5. This metric reflects the ability of citizens to freely use the internet without fear of privacy violations, identity theft and online attacks".
The survey showed that, in terms of safety in Southeast Asia, Thailand (Bangkok) was, in fact, a close second to Singapore and was better than Malaysia ( KL). So your initial claim was, as I suggested, completely without foundation.
