Yup, it took a lot if international cooperation to actually get the guy which is why she was thanking so many people not from this country. Knowing the rough geographical area where he is doesn't mean jack, especially when it's in a foreign country. You have to work with foreign police and investigators to track down exactly where the guy is and to apprehend him. That's not an easy task. Contrary to initial reports, he wasn't just sitting in some cell waiting to be captured. The guy at the very least is a pedophile, so kudos to the Thailand law enforcement for assisting with his capture.
I know he wasn't sitting in a cell; it's not like authorities got him on their own and through lots of legwork. They got him because he made the stupid mistake of e-mailing Patsy Ramsey. He was in Thailand under his own name and wasn't difficult to find or trace.
Thailand is practically pedophilia central and they wouldn't have done squat to him if the US hadn't wanted him on a potential murder charge or if he hadn't been convicted in abstentia on the 2001 child pornography matter.
