I appreciate you providing a well informed comment. Other than James Bond Q level gear, there's no way the Brown Shirt spook could have fired a palm gun with any hope of accuracy. A camera wirelessly linked to his goggles with an HUD display of the sight picture from the palm gun is not particularly difficult to make today. We've had similar tech for decades in tanks and planes, so it's not incredible for spooks to have much smaller sight systems suitable for such a covert palm gun. Google lens has been around for years, and spooks have much better gear than what is available commercially.

However, I think it's AI, and don't think the Brown Shirt spook is real. I want proof it's fake, and I think that shouldn't be beyond expectation because there are a lot of cameras taking video of that event, which can establish a consensus of real video that proves this video is fake. Also the analysis of that video can possibly locate the actual shooter. But, that doesn't have anything to do with Tyler Robinson, who couldn't have shot Charlie Kirk without the rifle the FBI says he used (unless they're hiding some other weapon that was used from us).

In the pics of Robinson going up the stairs, his pants are so tight you can clearly see his cell phone in his front pocket, and that's less than 1/2" thick. There is absolutely no way he had that rifle in his pants, even with the stock separated from the action and barrel. It would print visibly, just like his cell phone. Whether polymer or wood, the stock is one piece, ~30" long, ~6" wide at the butt, and ~2" at the termination of the forend. It's a long action Mauser with a 24" barrel, making the barrel attached to the action at least 30" long. With the scope attached to the action, it would also be well over 6" wide, too. According to his booking pics, he's 6' tall, 72". His backpack isn't 30" high and couldn't hold either piece of the rifle. Even if he had a hole in the backpack from which the barrel and forend of the stock could protrude, and stuffed them down his pants, they'd print. He's wearing tight pants. The forend is at least 2" thick at it's termination, and if that pack is ~18" tall (my daypack is ~14" tall), both the forend and the barrel would protrude >12" down his leg. They would be obvious. He neither had anything large enough to be that solid stock nor the barrel and attached action when he dropped off the roof. He had something much shorter, about the length of a scope (but thinner), perhaps, and some cloth like a towel.

"I don't know if we have footage of him actually entering the school."

WE don't. The FBI does. The Losee Center has just been extensively remodeled, and has brand new HD cameras that cover every place where Robinson is said to have been on the grounds of the center, including the roof, where the FBI claims he fired the shot from. The FBI should have video of every moment Robinson was on the grounds of the Losee Center, including where he posted up to fire from. The video of him running across the roof is deliberately cut so that it doesn't show him getting up, changing clothes, or breaking down the rifle, despite there should be video of him doing those things because the new cameras cover the entire roof. The pics in the OP are screencaps from surveillance video that show him walking up the stairs to the roof. One of the most suspicious things about the pics in the OP are that they seem to be deliberately chosen NOT to show Robinson's face clearly. What they do show clearly are his tightly clothed legs and upper body (his shirt is close fitting too). There is no rifle printing under his clothes, and it wouldn't fit inside the backpack even broken down into two pieces.

It occurs to me (and not only me) that the weird claim he changed clothes multiple times is an attempt to explain away people wearing different clothes in the surveillance footage, because Robinson wasn't alone and the FBI wants him to be a lone assassin. That adds to the suspicious screencaps that don't show Robinson's face clearly, and the fact he doesn't have a Mauser long action .30-06 with him when he goes up to the roof, nor when he jumps down. The barrel and attached action would be almost half his body length, which the cloth and item he did have was nowhere near. What he was carrying in hand appeared to be able to fit in his backpack, in fact, so less than ~18" long.

Here's the pic the FBI provided of Grandpa's '06, they claim was the assassination weapon. You'll notice right away the scope is mounted wrong, and more likely to blacken a shooter's eye than hit anything he aimed at. However the barrel is 24" long, and threads into the action ~1" forward of the front ring clamping the scope to the action. It's half the overall length of the rifle, which makes the stock >30" long, and it's one solid piece, as you can see. The Mauser long action also adds at least 6" to the barrel length. That's not what he had in hand when he jumped off the roof. What he had was not anything as wide as the action or the butt of the stock, and not as long as either action or stock.

"...when you zero a sight/scope you're typically doing it for a certain distance..."

Yes. I typically sight in an '06 for hunting hereabouts at 200 yards, because then it shoots ~1 1/2" high at 100 yards, and ~2" low at 300 yards (with slight variations depending on ammunition), making every well placed shot in the ~6" kill zone on a deer from zero to 300 yards without even adjusting for ballistics. That would be about perfect for the range at which the FBI claims Charlie Kirk was shot, too.

You're absolutely correct that if he detached the scope there is no way he'd shoot accurately. A head shot <200 yards isn't particularly difficult. But even just detaching the barrel and action with the scope still attached from the stock would negatively affect accuracy. I can print a 1" group at 200 yards with a rifle that can do it. One of the things I learned to do was 'bed' actions tightly into stocks, and free float barrels, to eliminate vibration/harmonics from variable movement of the stock relative to the barrel where they're in contact, and get rifles to shoot that accurately. Making that shot after detaching and re-attaching the scope is almost impossible - but even just breaking down the action from the stock would make that shot unlikely, because it wouldn't be possible to precisely reattach them to exactly the same position and tightness the rifle was sighted in with, which would add a minute of angle or two to the group at that range. An inch or two at 100 yards, and that shot was ~140 yards IIRC, spreading the group even wider. I would never voluntarily do that hunting, for example. I don't think any of that matters though, because looking at the pics of him climbing the stairs, there is no place for him to have that rifle with him, and he didn't drop off the roof with it either.

Thanks!
