Laser-guided, drone-launched, smart projectile sniper system explained

Whether the specific premise of this video is right or not, the weaponry discussed is real and probably decades behind what is available to state-level militaries today. I expressed speculation along the lines of this video soon after Kirk’s assassination. All of this is speculative. I found this video interesting because the weaponry is very effective and part of our world today. Lack of a visible entry wound on Kirk makes it unlikely the fatal projectile came from Kirk’s right. So far, every hypothesis has holes in it, including the official story. Is there a projectile that is very small and can enter like a needle and then expand and explode on exit in a way that would fit what we have seen on videos of the assassination? ABN
