    I wish I was an engineer, but I have read a few mechanical engineering books with chapters on gears, and it really is a bottomless pit.

    In the example, I recall seeing a method a ways back where 3 interlaced gears could rotate simultaneously. Two are linked traditionally, while one is a helical gear that slides though the teeth of the other two. It had a slick animation, wish I could find it.

    That’s a complete fabrication.

    First of all, I was unable to find a source showing that Charlie was wearing body armor.

    Second, body armor is not made out of steel plate for exactly this reason. Body armor is usually ceramic plates that are designed to dissipate kinetic energy by fragmenting, covering in a plastic or polymer jacket to catch and slow down any fragments, and then it’s usually in a kevlar (or other strong filament) carrier to further catch fragments.

    If a round had hit his chest, and then ricochetted up into his neck, then there would be very obvious evidence of this. His shirt would have a decent entry hole, plus a big debris pattern of lead and jacketing material from where the round hit the steel plate. There would be a much larger and more ragged exit hole, more likely multiple, since bullet would have flattened and fragmented on impact with the steel plate. There would be a lot of smaller wound in his neck from the bullet fragments, instead, we get one clean hole.

    To sum it up, he wasn’t wearing any armor. Even if he was, body armor is made to catch bullets, not deflect them into your neck. And if that did occur, then there would be multiple obvious signs that it did happen that way.
