My dad (bless his soul) suspected LBJ too.
My Dad did too. A lot of LBJ's buddies got caught up in RFK's mob stings. Me, I wouldn't put it past Johnson, but I think Oswald did it.
So did my Mom
LBJ was a bad guy - my mother in law read some things about him way back when - and she was horrified.
My wife still does. I'm ambivalent about the whole thing. Old enough to remember it (Second grade, it meant no cartoons for three days!) but long past by the time it become more than a kid's personal inconvenience.
Death bed confessions are admissible in court I believe (not sure) and this could change things.
OTOH, it's well into the "Shinbone Star Theory Of The West" realm. "When legend become fact, print the legend". ;)
I just don't care. At this point in time it's simply another way for the Democrats and their Socialist puppet masters to tear down our country.
Leave it be.
I still do.
LBJ was the ONLY one that BENEFITTED from JFK’s death.
