I voted 'No' but actually I'm of the opinion that Oswald was not even aware of what would occur that day. He, however, soon became aware that he was being set up.
Head shot is what did in JFK. There is not argument regarding that. The number of shots fired is in doubt regardless of who does the counting.
Since that day one thing has bothered me... Just like WTC7's 'Free Fall Drop' years later... Why would Oswald wait until JFK was in line with the tree that was in Oswald's LOS to fire...? He had a clear and perfect shot prior to that last turn... IF he was of a mind to commit the crime it seems to me he'd not wait for the vehicle to be in the least favorable position to commence his activity.
I've read and reread every interview, every bit of testimony from all of the inquiry events. It simply don't add up...
The thing is, that issue doesn't prove any version - it can be consistent with conspiracy or not, even if not equally likely.
One error in looking at these issues is to expect no surprises, unlikey things to happen. So, if the first shot was better, then he *had* to have taken it. But he didn't.
There are any number of reasons he might not have. A hesitancy because he was about to kill the President, a noise that distracted him, a cough, a problem shooting in the face.
Of course that's also consistent with 'being in position for a 2nd shooter in the railroad area', but isn't proof of that.
Remember, the guy opening the big black unbrella 'made no sense either' and some said the only thing that made sense was signalling shooters - but no, the unlikely explanation was the right one, the coincidence that someone used that very unusual method of political protest. What are the odds - a protest so rare no one I've seen has heard of it, right with the assassination?
As I said, IMO, it makes a lot more sense to ask if there were people in a 'conspiracy' outside the shooting. For example, telling Oswald to meet them for a phony 'getaway'.
It has been about 47 years now and folks say 'move on already'... hehehehehe Why? Is that not exactly what the bad guy expects you to say... assuming there is a bad guy or guys...? You move on if you wish... I'll keep the events of my life time that don't add up.... Gulf of Tonkin for instance... among many others.. so that when some folks state .. "the air is clean to breathe".. I'll quick get a gas mask... cuz our leaders have said that before in the face of absolute evidence to the contrary... You trust who you wish... I'll trust me... I believe me... I'm hard pressed to accept anything that don't add up from anyone... WMD comes to mind..
Golf of Tonkin is pretty crazy. Of course it was just a cover for starting the war - and apparently involved in the one shooting that did happen, North Vietnam shooting at our destroyer in *their waters* as it was escorting a small boat of US-trained terrorists into North Vietnam, as our destroyers often did.
I've heard the audio of an admiral asking for answers at the time from a local officer, and it was very confused - while the President was apparently assured it happened.
Isn't it funny how often this 'who fired the first shot' issue has been the trigger for wars, to the point presidents have arranged for the other side to shoot it?
Lincoln did that at Fort Sumter; for the Mexican-American war, the president ordered a group of cavalry to sit around deep in Mexico on the 'new' border, until about four members of the unit were off riding when they ran into a big group of Mexican military who confronted them as the trigger for that war. Even in WWII, there's evidence of FDR trying to get the Japanese to attack first, even if he thought it would be minor, not Pearl Harbor.
And we we have a hard time getting the other side to shoot first, there are 'false flag' operations. Operation Northwood was one such proposal to justify invading Cuba; many accounts in the 60's of peaceful protest movements found government undercover infiltration where the government operatives were the ones advocating or committing violence, creating the chance for the government to use strong force 'in response'.
Remember the trigger used for the Panama invasion - the claim a few members of the Panamanian military had beaten a US serviceman and threatened his wife. Start the war!
