Grassy knoll=diversion

Uh-huh.

And it also could be as simple as keeping uncertainty alive.

Yup! They do do that, don't they. For example, on the shot from the fence/knll area - while overall they from the beginning chose to discredit all that evidence/witnesses, as it has become more emplaced into mainstream discussion/acceptance of what actually happened, TPTB have tried to cloud the issue/facts by inventing [IMHO] additional fence/knoll shooters - to try to discredit and dilute the real ones [and playing both sides of the fence, literally and figuratively]...as Charles calls it "keeping uncertainty alive". TPTB do NOT, repeat NOT, want any conclusion nor certainty on what happened that day - let along why. They continue to move the mirrors and blow more smoke, as well as try to discredit, thwart and on a few occasions killed those who would/could speak the truth, in some form. hutup:

Overall, in the society at large, they have created great doubt, but have not stopped the research community, nor determined and open-minded non-researchers from approaching the truth of what happened. The EXACT truth may well have been so buried with disinformation/destruction of evidence and witnesses to ever be fully reconstructed. I feel, however, we can and have gotten a more-than-sufficient 85-95% clear view, today.
