Point of order, but Alfred Stelpstra, the Canadian teacher who was struck off for having child pornography on his computer after being caught in a wider kiddie porn network bust, and who escaped prison because of a technicality, doesn't actually live in Siem Reap.
He just visits Siem Reap regularly. The fact that Siem Reap seems to have been the centre of a disproportionate number of very high profile kiddie porn and child sex cases featuring expats in the last few years likely has nothing to do with the fact that Alfred Douglas Stelpstra visits the city so regularly. I repeat, nothing to do with it. That's completely coincidental.
