Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

I am now certain that JFK was hit with a nerve agent. There is NOTHING ELSE that can explain his bizarre physical and mental behavior as seen in the Zapruder film. And there is NOTHING ELSE that can explain the shallowness of the back shot. A bullet reaching him over the distance it had to travel, would surely have had enough energy to tunnel deeper into his back than one inch. However, a frozen dart, and you should think of it like an icicle that was designed to burst as it impacted him, that would travel a mere inch because when the ice burst, it dissipated the energy. That's where the energy went- into the bursting. Plus, if the ice bullet burst, there was no bullet left to keep tunneling. Once it burst, the little pieces would have melted to liquid very quickly. It was designed to work that way and to feel like nothing more than a mosquito bite. And it was described that way at the Church Committee in 1975. Why the members of the Committee didn't ask themselves whether it was used on JFK in 1963, I do not know. But, I do know that it WAS used on JFK in 1963.
