I read the daily anouncements from 'Asean Now Daily News'.All seems bad ref foreigners killed or scamed in Bangcok and Phuket.
Been Thailand many times and never been above places (except hotel at airport), but travel north to places in the countryside. Never had any issues and people are lovely. Moral is, if you go to places where you know there are problems then expect the worse, or avid them.......... It aint rocket science
And yes, RIP, it is wrong this happened
