I keep seeing FKR say, “ARCCA proved John wasn’t hit by a Karen Read's Lexus.” If you still believe that myth, then go and rewatch Dr. Daniel Rentschler’s testimony and listen to how he described the scope of the testing: “We were constrained [by] what the client [Karen Read] wanted to know. And so we tailored the test to do that…” On cross, Rentschler acknowledged that he didn’t factor in the Apple Health, iPhone, or Toyota Techstream data. He didn’t examine the distribution of taillight fragments or the microscopic fragments recovered from John’s clothing. His analysis didn’t account for where John’s hat and shoe were found or how the broken cocktail drinking glass, the shards of glass in the street, and the microscopic taillight fragments embedded in John's clothing fit together. Rentschler called the location of John’s hat “immaterial” to his biomechanical analysis. When asked whether he examined the microscopic fragments from John’s clothing, he answered: “No, I did not.” Then there’s the double standard on arm position. Rentschler strongly criticized Dr. Welcher’s blue-paint demonstration because nobody knew exactly how John held his arm. When Brennan pressed him on whether Welcher had ever claimed to be recreating the collision exactly, frame by frame, Rentschler conceded, “He did not state that. That’s correct.” Welcher was checking whether John’s arm COULD have lined up with the damaged portion of the taillight. New flash: ARCCA didn’t know John’s arm position either. It tested with the dummy’s arm in only one position -- held straight out. If uncertainty about John’s posture limits what Welcher’s demonstration can establish, then that same uncertainty limits what ARCCA’s test can rule out. If you submitted the “we tested the dummy with its arm straight out, therefore the Lexus couldn’t have clipped John” theory to a peer-reviewed journal, a reviewer would spot the leap in a New York minute. So when someone says “ARCCA proved it,” ask one question: How does a test with the dummy’s arm held in one position rule out contact when nobody knows where John’s arm position actually was? mabbe8.substack.com/p/arcca-…
