What happened to innocent until proven guilty? lol
This is not a criminal trial, so that standard does not apply.
This site seeks to verify all information relevant to the Race while it is filming, and thereafter. People have tried in the past to get false sightings through, and that is one reason why everything has to be vetted. And even then, something could be missed.
More often it's identifying that season's Racers, but the twist made that part easy. But the westward start to Asia is always problematic with sightings and extra diligence has to be taken to make sure the information is correct, that images are properly credited, and sensitive material is not posted.
There's not much I can do during filming except draw on my experiences where TAR is concerned going back to the beginning, and apply reasoning to be sure avenues are not overlooked. So that is what I do.
For what its worth, I don't expect the teams to leave Laos using the same connection they came in on; just a gut feeling it would require multiple connections to go elsewhere through Hanoi.
