3 Bikers Audio Pin
An Audio Pin is a technique used by Forensic Linguists, Computational Linguistics and Forensic Animators to compare witness statements. The principle is simple: by using a computer voice (to insure consistency), the timing of statements can be standardized to remove rhythm biases. Next, the statements are "pinned" to a common word or phrase, and inconsistencies or contradictions become obvious. Audio pins are routinely admissible as defense and prosecution exhibits, and do not require expert witness corroboration (they are exhibits, not evidence).
In the three biker's problem, the "snap" or "break" neck statement is the only consistently heard (or fabricated) statement by all four parties-- pedestrian, plus three bikers. See the output pictures below. When pinned, it becomes obvious that at least two of the bikers (biker one and biker three) are fabricating large parts of their statements, and biker two is fabricating that he missed parts of pedestrian's statement. The large "extensions" seen on both sides of the audio pin diagram should be overlaps if the bikers actually heard, rather than fabricated, multiple statements by pedestrian. The third animation on the home page shows how absurd biker one and biker three fabrications MUST be, as pedestrian would have had to make multiple overlapping statements for the biker's police statements to be true!
After looking at the pin, page all the way down to see the BIKER CONTRADICTIONS DIAGRAM based on the pin.

Directions: Click the Word File on the Right (CHOOSE OPEN in the dialog box) AND see the exhibit at the bottom of this page to view the contradiction diagram based on the above audio pins. When asked why the police didn't cite the bikers for reckless speeds on the blind hill on pedestrian's property, police said they would have to observe it. Then, when asked why they were citing pedestrian when they also didn't see the incident, the police said "it's three words against one." The diagram shows just the opposite-- it is NOT three words against one at all! Pedestrian and Biker 3 agree that it was a blind curve vs. the other two; Pedestrian and Biker 2 agree that is was only a short 9 word statement vs. the other two, and when all the conflicts are removed, pedestrian's version remains as the only possible version, even without the poly, and on the face of the biker's own statements! Biker three heard nothing at all.
