I haven't read every post in this thread so maybe this was brought up before; if so apologies.
Just to fuel all the speculation, here's another angle by which this matter could be examined. The study of body language and micro expressions is a fascinating topic.
Programs like this show experts analyzing footage of public figures and pointing out telltale signs of lying and truth telling. I have no doubt that a body language expert could look at the video of Telesforo and determine in a second whether the WR claim is legit.
In short, they would be asking themselves if Telesforo's posture, hand movements, facial expressions, words, tone, behavior, etc. are ALL consistent with someone who just broke the 3x3 WR. For example, in the Watergate trial, Nixon was speaking sternly and defensively (anger and frustration at the accusations, consistent with his claim of innocence) but wringing his hands behind his back (inconsistent, showing nervousness and doubt).
Now if any of you are actually proficient at this skill, I'd love to hear your opinion. If you're not an expert and this sounds interesting and you want to try analyzing the video yourself, some things to keep in mind: try not to go in having already formed a conclusion; please be honest about your noob status and realize you and I are making little more than guesses.
Whatever, it's a fun exercise =) Maybe something worth paying attention to in your everyday life. [That documentary linked to above is worth checking out!]
