An analysis from the federal Bureau of Alcohol, Tobacco, Firearms and Explosive (ATF) could not conclusively connect a bullet fragment recovered during Charlie Kirk’s autopsy to the rifle found near the scene of the rightwing political activist’s killing – and the FBI is running additional tests, lawyers for Kirk’s accused murderer said in recent court filings.

In the court filings, Tyler Robinson’s defense team also asked for a delay to a preliminary hearing scheduled in May, saying they need time to review the bullet analysis as well as an enormous amount of other material that could contribute to the suspect’s defense.

The ATF’s bullet analysis report has been kept private, but attorneys have cited snippets in other public filings that say the results were inconclusive.

The defense said in its motion that it may try to use the analysis to clear Robinson of blame during the preliminary hearing while prosecutors aim to show they have enough evidence against him to proceed with a trial.

    I have read somewhere that the whole “bullet forensics” process is mostly pseudoscience anyway. A quick search found this article:

    https://www.scientificamerican.com/article/the-field-of-firearms-forensics-is-flawed/

    If a shell casing wasn’t ejected on the scene (like with a bolt-action not cycled) then all they would have to analyze is the what’s-left-of-bullet which is possibly just a mess of lead and copper. May or may not have rifling marks left on it

      Yeah, shits not like on TV.

      In fact, one of the big reason it’s like that on TV, is just so when cops lie in real life, idiots believe them.

      They consistently tell suspects “we know your gun fired the bullet” but they don’t, at most for handguns they can say “a glock fired it” because they use weird octagon rifling.

      Matching it to a specific firearm is impossible unless the barrel is real fucked up in a unique way.

      A 30-06 will have such massive deformation, I’d be shocked if any rifling is identifiable.

      That doesn’t mean the person they claim is the shooter really is tho, all types of shit happened immediately after that only make sense if there was a cover up.

      But anyone expecting a bullet to be “matched” to a rifle been watching too much CSI

        A 30-06 will have such massive deformation

        The article describes a fragment, which is beyond mere deformation. That’s unsurprising with a high-velocity rifle round and would typically be impossible to conclusively match to the weapon that fired it. It could be possible to exclude a particular weapon (wrong caliber, obviously different rifling, etc…).

          They don’t seem to be denying fragmentation/massive deformation. In fact, the crux of their comment relies on that fragmentation.

          That massive deformation of the bullet comes from massive force, that didn’t happen to kirk’s neck.

          The point is that, with the amount of force in applied to fragment this bullet, we do not see a similar amount of force applied to Charlie’s neck. There was no large exit wound, and the projectile did not appear to impact his spine.

          Article says “fragment”. Have you seen otherwise?

          Did the bullet stop in some conveniently placed ballistics gel behind Kirk?

              Hunting rifles like that are usually going to make a small entrance wound and larger exit wound. I haven’t seen exactly what happened to kirk because I don’t like to watch people die. But I can say from experience with deer hunting that it’s plausible for that rifle to make a narrow wound channel through a person, while being extremely deadly to them, not making a huge wound outside.

              Basically those high powered rounds are made to penetrate well through large animals, tougher than humans. Expanding and deforming of the round is intended to begin well after penetration, unlike the way handgun bullets are designed.

              So I think it’s totally possible that Robinson did it even though the bullet isn’t able to be matched

        I searched and couldn’t find any information about fingerprints not being admissible in any courts. I’ve found a lot of stories about how they aren’t 100% accurate (closer to 95-99 percent), but not one story about how fingerprints were not admissible.

        Where are these “many courts” that don’t accept fingerprints?

          Did you try?

          fingerprint evidence is not currently permitted to be reported in court unless examiners claim absolute certainty that a mark has been left by a particular suspect. This courtroom certainty is based purely on the opinion of experts

          https://science.psu.edu/news/barriers-use-fingerprint-evidence-court-unlocked-statistical-model

          Fingeprints are not admissable, just some guy’s opinion, because fingerprint identification has no real basis in science. And no, they aren’t 95-99% accurate (especially because it is just some guy eyeballing it), when tested by giving multiple “experts” the same set of prints, the “experts” come to disagreeing conclusions about if the prints match or not over half the time.

          You mean they bring in an “expert” to testify that the fingerprints match… and when you give 2 “experts” the same set of fingerprints to compare, they literally come to disagreeing conclusions in 50% of tests

          It is not a scientific or analytical process with scientifically identified “points of similarity”, its just a person who is deemed an “expert”, who looks at 2 fingerprints and says “yeah these look similar, and they look similar in X different places so 👍”

            There are the actual standards, then there are prosecutors perverting them. Prosecutors are the least trustworthy people on the planet. Total pieces of shit, no argument here. But fingerprints themselves aren’t junk science as I’ve read, not like past hair analysis, blood spatter, bite mark analysis, 911 voice recording analysis, or any number of other junk sciences. As I understand it.

            But don’t let me dismiss your point out of hand, what gave you this opinion, did you read something as such, you have a source on this?

      And even if it does, they’ll be so mangled as to be useless. Like you could say "ok the rifle has four grooves at 1:8” but you’ve got a fraction of a bullet that was squished into an entirely different shape on impact.

      Especially for 5.56/.223 where one of the major selling points is the cavitation it causes in soft tissue. “cavitation” being a polite term for “makes fucking explode”.

      Its why actual footage of mass shootings is so horrifying. Media (and video games that glorify it…) like to paint it as neat little holes when the reality is you have one neat little hole for the entrance wound and a giant fist sized one or larger for the exit.

      And all of that does a number on the bullet itself.

        … The official story is that Kirk was shot with a 30-06.

        A 30-06 is not a 5.56.

        The official story is that Robinson shot Kirk with a 30-06, his grandpa’s old bolt-action rifle.

        Why are you talking about a 5.56?

        That’s nowhere in the article, its not part of the official story / prosecution case.

        Gun “finerprinting” is and isn’t bullshit.

        The reality is that for a given configuration of a gun, you do get some rather distinct markings on a bullet. It is less “We can 100% determine this bullet was fired by this bigoted dipshit’s gun so let’s hand it to him so he can dramatically show he took the firing pin out” but you can get within a pretty high level of confidence.

        Unless… the shooter cleaned their gun. Even just field stripping can often be enough. Let alone if they actually remove the firing pin and reinstall it (not even replacing).

        I don’t believe anyone here was saying there was.

        You are correct though. It was obvious some conservatives wanted the execution, they just watched, to not be labeled an execution. “Self inflicted overdose” was a convenient excuse for them, so they ran with it.

            Ok, just to check I’m not being too obcure I put my initial comment into Gemini.I asked it to explain the comment in the context of a post about the bullet that killed Charlie Kirk. It doesn’t know Kirk is dead, it did get the joke though. Now to the article, would you like to read the initial paragraph again please… Perhaps copy it into your next comment.

            Prompt:

            Explain this comment left under an article about the bullet that killed Charlie Kirk:

            “I thought Charlie’s medical found lethal doses of fentanyl in his system.”

            Gemini:

            To understand that comment, you have to look at it through the lens of internet subcultures and political satire. It is a layered reference to the 2020 death of George Floyd and the subsequent memes that emerged from right-wing and left-wing online spaces. Here is the breakdown of why that comment was made:

            1. The “Lethal Dose” Trope The specific phrasing—“lethal doses of fentanyl in his system”—is a direct callback to the toxicology report of George Floyd. Following his death, many conservative commentators and social media users argued that Floyd did not die from police restraint, but rather from a drug overdose. By using this exact line in a comment about Charlie Kirk (a prominent conservative figure), the commenter is engaging in “copy-pasta” satire. They are taking a common right-wing talking point and “copy-pasting” it onto a situation involving a conservative to point out what they see as an absurdity or a double standard.
            2. The Context of the “Bullet” Article If the article mentioned a “bullet that killed Charlie Kirk,” it is likely referring to a viral piece of misinformation or a specific satirical news story. Charlie Kirk is alive; therefore, any article claiming he was killed by a bullet is either: Satire: (e.g., The Onion or The Babylon Bee style content). Misinformation: A hoax designed to trigger a reaction.
            3. The Irony of the Comment The commenter isn’t actually confused about Kirk’s medical records. Instead, they are using dark irony. The Logic: If a conservative argument suggests that a victim of violence actually died of a drug overdose to absolve the shooter/police, the commenter “flips the script” by suggesting that even if Kirk were shot, his “true” cause of death must have been fentanyl. Summary of Intent Mockery: To mock the arguments used in high-profile police brutality cases. Shitposting: To derail a serious or sensationalist headline with a well-known political meme. Parody: To act as a “mirror,” showing how certain political rhetoric sounds when applied to its own side. In short, it’s a cynical joke aimed at the way political deaths are litigated in the “court of public opinion.”

      Never. That is what it was though. Something similar to that anyway. We should all know it, but plenty on “the left” here silence questioning the obviously false on at least three points fbi information, officially because some on the right also questioned that evidence and therefore they are opposite of that.

        From your comment history:

        It’s also rumoured, for a long time, decades, that the US has kill switches in most of the world’s computers. A fusible link they can send a message to that bricks it.

        Yikes.

          I mean, the Israelis kind of had something similar for a bunch of pagers, but instead of bricking the device, they just violently exploded.

            That is one of many windows into your thought process including your response to me here. I didn’t even state an opinion on the conspiracy theories, you just got mad that you thought someone implied they doubted them.

    This story stinks, totally impossible story by the fbi on three counts at least. No shit they didn’t release the ballistics results, because that rifle would’ve made a very different more dramatic wound than whatever hit kirk.

      I found it interesting that after Joe Kent resigned from being Director of the National Counterterrorism Center, he went on the record to say that the FBI prevented them from investigating any foreign links to the shooting.

      Between this and the fake assassination attempt on Trump I’m convinced we need to just throw away the CIA and FBI.

      Yep.

      So many idiots here in this thread haven’t been following this story at all, they known nothing about the autopsy results.

      There’s no way a 30-06 from the range and angle that Robinson was at… makes the wounds Kirk’s body had.

        Yup. Said the exact same thing on the day. A 30-06 would have made a fist sized wound (bigger if it hit bone). The wound is consistent with a 5.56 or similar. Much smaller bore lower ft/lb projectile is more likely.

        Have we considered the possibility of multiple shooters? The gun that killed Kirk may not necessarily have been the one that was found.

        Just trying to avoid jumping to conclusions.

          That is precisely what I think is the case.

          I think Robinson was there, but he was being monitored, being shadowed.

          There are many more parts of the FBI narrative that do not add up.

      They didn’t release the ballistics results because it is evidence in a case that is in progress.

    FYI, Kirk was against an attack on Iran, and dared to equivocate Palestinian lives with those of genocidal zionazis, in the sense that perhaps the genocide was a little too heavy. Reportedly, Bill Ackman (head of US mossad zionazi division) tried to donate/persuade him to be more in line with GOP doctrine on the chosen genocidal supremacists, but was rebuffed shortly before the murder.

    Joe Kent, director of counter terrorism, who recently resigned from Government because Iran war is purely for Israel, said that he was denied access to “terrorism investigation” related information in Kirk’s death.

      Netenyahu has wanted the US to back Israel’s war with Iran for at least 20 years. Trump is the first president sufficiently cognitively challenged to do it.
      These people are opportunists, not 5D chess players.

    A disturbing number of people seem to be reading this as:

    “The bullet does not match the gun.” i.e. that there is ‘proof’ that the bullet didn’t come from his gun

    Instead of

    “They can’t say if it is or is not from the gun due to being a small fragment and not an entire bullet”

    It probably doesn’t help that there are a bunch of communities/subreddits who’ve editorialized the headlines to say ‘bullet does not match gun’ and the tendency of people to only read the headline.

      Under the requirement to prove beyond reasonable doubt, “they can’t say if it is or is not from the gun” is huge, having a gun becomes circumstantial, and requires additional evidence, and depending on the strength of additional evidence, a good lawyer maybe able to get him off the hook.

    This is a nothing statement. It just means that they can’t definitively prove what rifle fired the bullet. It’s something that happens all the time, and there’s plenty of other evidence for them to convinct. Plus that motherfucker is still worm food, so it doesn’t really matter anyway.

    Bullet analysis is circumstantial and pseudosciencey anyway so the fact they couldn’t get that in their favor is kind of weird.
