According to a new analysis,
[...] In this paper, simple one-dimensional dynamical models are uniquely applied to study in detail the fatal shot and the motion of the President's head observed in the film. Using known parameters from the crime scene, explicit force calculations are carried out for determining the projectile's retardation during tissue passage along with the resulting transfer of momentum and kinetic energy (KE). The computed instantaneous KE transfer within the soft tissue is found to be consistent with the formation of a temporary cavity associated with the observed explosion of the head, and subsequent quantitative examination of this phenomenon reveals two delayed forces at play in the backward motion of the President following impact. It is therefore found that the observed motions of President Kennedy in the film are physically consistent with a high-speed projectile impact from the rear of the motorcade, these resulting from an instantaneous forward impulse force, followed by delayed rearward recoil and neuromuscular forces.

Not unless they invent a time viewer. Or somebody kept some really stupid evidence.
There are a lot of events where the official explanation is much less than convincing, but this doesn't automatically make any of the alternative explanations correct. Often the verdict of history is "this is what was claimed", it's rarely "we have complete and convincing evidence". Sometimes the government is more interested in coming up with an acceptable story quickly than in determining the truth, and then they're more interested in not being caught lying. But this is never the claim of the conspiracy theorists, because they're looking for "enemy action" rather than "cover your backside". But both, of course, happen. I've been quite dissatisfied with the official explanations of "the Vietnam War", the multiple Kennedy assassinations, and the 9/11 assault. This doesn't mean I find any of the alternative explanations convincing. (In the case of the Vietnam "War" there isn't even an acceptable official explanation. We were just supposed to accept that it was inevitable or something without an explanation.)
My general feeling is that a lot of history is CYA and ID10T errors, with a bunch of conspiracies thrown in, which are occasionally influential, though not necessarily in the direction that they intend.
