Afew years ago, I covered a particularly odious court case in which a New Zealand man was convicted of organising underage sex tours to Thailand.
The detail was just as awful as you might expect, but I was struck at the time by how difficult it is for police in Southeast Asia to keep up with the thousands of tourists who visit their countries with the intent of abusing children.
It's a hideous thought.
In New Zealand and in other developed countries, it's our expectation police and government authorities will continue to monitor convicted sex offenders once they're released into the wider community.
For the most part, although there are occasional devastating exceptions, our monitoring and support systems for convicted child sex offenders are generally pretty good.
