I've never had more than a passing curiosity about the conspiracy rabbit hole that is the JFK assassination. When I saw recently though someone suggest the possibility that a Secret Service agent may have accidentally hit Kennedy I saw suddenly how that explanation seemed not only to put a lot of the puzzle pieces together (at least the more common quandaries you hear about) but seemed to me plausible as well.

Then again, with all things, it seems impossible they could have covered up something like that without someone leaking/talking.
