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

Now, I have a first-hand reference to the fact that the CIA heart attack gun could deliver nerve agents. Mary Embree, who was a CIA agent, not a field operative, but a researcher and administrator. And she said that the heart attack gun could also deliver shellfish neurotoxin, which paralyzes muscles. I have watched the video in which she talked about the neurotoxin.

I don't know who operates this Conspiracy Wiki website, but you'll notice that after describing the toxin, he presents a list of possible victims, and one of them is John F. Kennedy, who suffered an "unexplainable wound," and which refers to the shallow back wound.

Now, let's talk about shellfish neurotoxin. The toxin is produced by algae, and it's not an uncommon occurrence in Florida, where it is known as a "red tide.". 

The toxins are known as brevetoxins, and they interfere with the sodium channels resulting in neuro-excitation.  Read here about neurotoxic shellfish poisoning.

The first symptoms are numbness and tingling. That's followed by ataxia, which refers to the loss of control of bodily movements, which JFK exhibited in the back of that limo, where he couldn't put his arms down. Speaking difficulties, disorientation, and seeming to be intoxicated follow, and that all applies to JFK, who couldn't speak, was obviously disoriented, and appeared to be suddenly intoxicated. 

Just look at the man. He can't unflex his arm. He is out of it mentally, and not from traumatic brain damage because that hadn't happened yet.

Kennedy was hit with a nerve agent. That's what the shot in the back was all about. That's the reason it was so shallow and went unnoticed at Parkland. The physical trauma done to him by bullets cannot explain his bizarre behavior.  It was caused by a toxin delivered by the heart attack gun. And it happened high on the hill, just past the TSBD. It hit him just before the Croft photo was taken, where you see the elated, smiling African-American women waving at him. 

JFK was already hit in the back there, and not with a bullet, but a neuro-toxic dart.  And at that point, the limo was traveling very slowly, giving it time to seep in.
