There are only two things on that list that would be relevant at all to the assassinations, and they are items about civil rights and the secretaries warnings. And the secretaries warning's didn't even happen, so the only similarity that would have any relevance to them being shot is the civil rights thing. The rest of the stuff on the list is completely irrelevant and about as convincing as the "type these letters into word in this font and it looks like the WTC!!!!" conspiracy theories.
What the list does show, however, is that civil rights was an incredibly controversial topic that people were willing to kill and be killed for.
