It's first about evidence.  In these days of misinformation, disinformation, conspiracy theories, everybody saying what they please on the internet as if everyone has an equal say about what is true, I remind you that you should have good, defensible evidence for your truth claims.

The subject of the assassination of President Kennedy in 1963 has come up twice in my recent conversations with intelligent friends.  Just happened to come from them, not me, since this is not a subject I dwell on, but it still seems to be fertile ground for conspiracy theories for those of us old enough to remember.

One friend said he thinks Lyndon Johnson was behind the assassination.  Oswald may have been the shooter, but LBJ was behind him.  His reason?  The VP had the most to gain by Kennedy's death, after all, making him President.

I asked him do you have any or can you point me to any credible evidence that LBJ had anything to do with it?

No, he admitted, none whatsoever.  Whereupon I changed the subject.  Sloppy thinking like this is rampant these days.
