Kirk Assassination ATF Expert Admits the Fatal Bullet Cannot Be Matched to Robinson's Rifle | Pt 20

An ATF ballistics expert, called by the defense, just admitted under oath that her entire science has a massive, shocking error rate. We are back on the ground in Provo for Day 4 of the high-profile Charlie Kirk murder trial. The defense called ATF firearm and toolmark examiner Samantha Carer to the stand to expose the strict limitations of the state’s ballistics evidence. In a series of stunning concessions, Carer detailed how the Department of Justice explicitly bans firearms experts from claiming absolute or scientific certainty in a courtroom. Carer’s testimony walked the court through the Department of Justice's Uniform Language for Testimony and Reports (ULTR). Under direct questioning, she admitted that she cannot claim an identification is based on "uniqueness," cannot use the term "individualization," and cannot assert a "zero error rate." With Tyler Robinson facing capital charges for the campus shooting of Turning Point USA founder Charlie Kirk, the defense used the state’s own expert to show that the ballistics matching is an opinion, not an objective, statistically derived measurement. The climax of the direct examination came when Carer was asked about her own proficiency testing. She admitted that on a 2023 bullet comparison test with a high national error rate, she answered "inconclusive" when the actual ground-truth answer was "exclusion"—meaning the bullets did not match. Yet because her lab’s guidelines accepted inconclusive answers, she was still graded as "satisfactory." If the state’s foremost ballistics expert cannot confidently spot a non-match in a controlled test, how can the jury trust her conclusion on the fatal bullet fragment? --- WATCH WITH JUSTICE 00:00 - 08:09 Judge Establishes September Bindover Schedule. Judge Tony Graf manages the family's plea to view the enhanced surveillance video in the courtroom and overrules defense objections, reserving his final ruling for tomorrow while calling the defense's first witness, ATF examiner Samantha Carer. 08:09 - 18:05 ATF Examiner Details DOJ Banned Language. Under direct examination, Samantha Carer explains the Department of Justice's uniform language guidelines, admitting that firearms examiners are explicitly banned from claiming 100% or "scientific certainty" in their reports or testimony. 18:05 - 30:25 Judge Admits 47-Page Case File Over Objections. Over intense prosecution objections that the notes are "more confusing than probative," Judge Graf overrules the state and admits Carer's entire 47-page case notes (Exhibit 6) containing the physical measurements of the fatal bullet jacket fragment. 30:25 - 47:49 The ATF Examiner Explains Subclass Characteristics. Carer details the difference between class, subclass, and individual toolmark characteristics, admitting that subclass toolmarks from the manufacturing process can be easily confused with individual markings. 47:49 - 1:11:34 Carer Concedes Science Is Subjective Opinion. Under direct, the ATF examiner concedes that the entire AFTE theory of identification is subjective, based on her own personal opinion of "sufficient agreement" rather than a statistically derived measurement. 1:11:34 - 1:20:41 The Shocking Proficiency Test Admission. Carer admits that on a 2023 bullet comparison proficiency test with high national error rates, she answered "inconclusive" when the ground truth was a direct exclusion, yet was still graded as "satisfactory" by her lab. 1:20:41 - 2:06:15 The Cross and September Briefing Schedule. On cross and redirect, Carer defends her holistic approach to bullet comparisons, after which both sides agree to submit written probable cause briefs in August, setting oral arguments for September 1. --- COMPLETE CASE COVERAGE justiceisaprocess.com SUBSCRIBE for daily trial coverage and hit the notification bell so you never miss testimony.
