Who said anything about a patsy? My comments are mainly to take exception with your claim that its an elementary level shot.
I shoot a lot of bolt action rifles dude, and have a pretty good idea of what they are capable of and how fast most people can run them. I don't own anything nearly as shitty and rough as that Carcanno rifle Oswald had , and I'm quite sure my modern Nikons and leupolds are leagues above whatever piece of shit 1950s era optic he was using. I wouldn't feel confident that id pull that shot off cold in those circumstances with that equipment.
Just saying that most people aren't gonna hit a volleyball 2 outta 3 times in 6 seconds while its moving at 10 mph with a sloppy bolt gun and shit scope. Add in the extreme stress of that situation, and its hardly a fish in a barrel scenario.
Honestly Your time with a Semi auto M4 shooting at stationary silhouette targets makes you and I about equivalent experts on the matter.
I happen to shoot a lot of bolt actions also! It's completely possible for someone to run that weapon like he did, especially an owner. Sure, if you put someone who's never handled the weapon system before, they will likely run it slower than he did. That's ignoring the fact that he purchased the weapon new, so any wear on the weapon is from him using it. Which means he was most likely proficient in the weapon system and any "shitty" parts of the rifle were something he was intimately familiar with.
And anyone calling the weapon shit pretending like a rough looking firearm isn't a deadly firearm clearly hasn't seen the weapon systems being used in the world today. I've found some shit fucking rifles in caches overseas that would fire perfectly straight for that distance. And I've actually done a decent amount of shooting on moving targets. The target isn't moving out of his scope that quickly from the angle it was moving away from him.
Let's also not forget that he probably wasn't aiming at the President's head. He would have at least been trained to fire center of mass. He likely hit higher than he actually aimed, either by chance, luck, or idiocy. So he was most likely aiming at a target way larger than a volleyball.
Combine that with the fact that 3 shell casings from the rifle were found there. The rifle was found there. He brought something shaped like a rifle into work that day. He ran from the scene. He murdered a cop who pulled him over after fleeing from the scene. And a dozen people heard the shots and claimed to see his rifle in that exact window. Then modern ballistics clearly show that to be the origin of the shots.
I'm sorry, but Carlos Hathcock is a fucking clown for saying that shit. You're talking about a man who made a shot at 2500 yards with a fucking heavy machine gun converted to a long range weapon claiming he couldn't hit a human sized target at 100 yards moving at jogging speed straight away from him? Just fucking absurd. That was an elementary shot for anyone trained to shoot at humans hundreds of yards away with iron sights.
I'm sure there was a deeper conspiracy with Jack Ruby and some other people, but LHO definitely made those shots for whatever reason.
