But it's easier to blame one guy than deal with all the unanswered questions if you don't accept that idea. Reality is that we will never know.
There's no "magic bullet," when you line Kennedy and Connally up correctly. The path is a straight line and the bullet never hit any bone until Connally's wrist, where it was significantly slowed down. And lead was discharged from the back of the casing and the bullet is deformed.
The JFK assassination committee in the 70s absolutely did not overturn the conclusion of the warren commission. That tells me you didn't even read it. They concluded a conspiracy solely on an audio recording that was later shown to be from a different time period than the assassination. The committee otherwise pretty much confirmed the conclusions from the warren commission.
Here's my conclusion after reviewing both sides very thoroughly: there is no evidence that anyone other than Oswald shot the president.

That is the oldest line of BS ever. There isn't a bomb in his head, so energy and momentum need to be conserved. A shot from the back will never result in the head being pushed backward. Part of his brain went out the back - exit wound, that's what Jackie was climbing over to get.
It seems likely he was shot from both directions.
But all of this discussion is rather silly because the government itself has accepted that more than two bullets entered the president and the governor and they could not have all come from the book depository window.
Here's video by CBS and Dan Rather showing their tests where they easily reproduced the shooting that Oswald did under nearly identical circumstances, repeatedly: https://www.youtube.com/watch?v=ghmY6HmR4fs

The key error in the HSCA investigation was timing; their analysis stemmed from a mistaken belief in both the timestamp of the recording and the position of the motorcycle doing the recording.
It's too bad I don't know how much data is still available, but network analysis of some past conspiracies (or claimed conspiracies) and released FBI, etc. docs could prove interesting.
