here for optimism. sergeant sinclair, it would seem, was vindicated. he said they were coming right all the him. the new evidence suggested that sinclair had hit the brakes, not because he was going too fast, as the highway patrol contended, but because he saw danger ahead. the california highway patrol investigators dismissed the new evidence, calling it the phantom skid mark. the chp experts covered that ground on their hands and knees, literally inch by inch, and never saw that skid mark. why they didn t find it wasn t clear, but the discovery gave new impetus to brunn s team of forensic accident reconstruction experts. paul kayfetz, a photographer and engineer, is an expert in something called photogrammetry. it s a $6 word for making measurements from photographs

argued it was made by the left. if they were correct, it meant the secret service could not have been over the center line. using photogrammetry, kayfetz was able to determine the width of the tire that made the skid mark and prove that it was, in fact, the right tire. as it happened, the right front tire on the wrecked labarge car was almost an inch narrower than the other three tires. it had been replaced probably by a spare tire at some point. and that particular tire mark matched only that narrower right front tire. proving the skid mark belonged to the secret service car was one of two critical issues facing dr. blythe. what was the sheriff reacting to when he applied his brakes? was he reacting to his perception that he was going too fast to make the corner, or was he reacting to some other danger

in fact, she could not. from the beginning, the critical question in the case was always, why did deputy sinclair jam on his brakes? kayfetz s dramatic re-enactment answered the question. now, from sinclair s viewpoint, we can see that he sees the lead secret service car straddling the center line just a bit more than a second before he begins to skid in a straight line across the highway. the last view is that of agent labarge just before the fatal crash. based on kayfetz s powerful reenactment and the work of brunn s team of investigators, a judge ruled that the secret service agents were partially responsible for the accident. he also ruled that the united
