I think it really don't matter if JFK was an assassination or not or if 9/11 was an inside job who knows what those 2 events have triggered that could affect our existence in the future.Even the most insignificant change can make a world of difference just like butterfly effect.temporal recon
Do we have an obligation to allow JFK's assassination?
I do tend to lend myself over to conspiracy theory just a tad bit too much sometimes. But JFK's assassination along with 911 really could use a thorough investigation if and when the advent of time travel technology becomes a reality. All the evidence and all the players in both events need to be thrown out on the table for scrutiny by all. Only then could a qualified answer be provided to answer your question.
In order to obtain untainted evidence, I would suggest three investigative teams, each independently run. Perhaps a group run by the government, one run by the people, and a totally unbiased group possibly comprised of individuals from abroad that have no ties or vested interest in the outcome of the investigation.
