Question regarding "Tabloid Junkie" lyrics

[Mr. Been Told]

Hi everyone,
I'm listening to Tabloid Junkie and there's one line I totally don't get.
Appearently it's something like:
Truth be told, the grassy knoll.

What in blazes does that actually mean?

I mean I know what a grassy hill/knoll is, but what exactly does that mean in this context?

[Sasha01]

Well, :hmm: knoll means a small hill, and since it's grassy.. :huh: Whaat? :blink: Is there sumthin' in the hill? :lol::mellow: This is interesting, I don't know what it means either. :no2: Coolies.

Speculate to break the one you hate
Circulate the lie you confiscate
Assassinate and mutilate
As the hounding media in hysteria
Who's the next for you to resurrect
JFK exposed the CIA
Truth be told the grassy knoll
As the blackmail story in all your glory

It's slander
You say it's not a sword
But with your pen you torture men
You'd crucify the Lord
And you don't have to read it, read it
And you don't have to eat it, eat it
To buy it is to feed it, feed it
So why do we keep foolin' ourselves


EDIT: AHHHH. Okay, I get it. Here. (http://www.assassinationscience.com/johncostella/jfk/intro/)

"This seems to tell us that the shooter was in front of the car on the right side, on the “grassy knoll” (small hill) next to Elm Street. But the U.S. Government insisted that JFK was shot by just one man hiding in a building far behind the limousine."

There's some graphics images soo.. yea. :unsure::mellow: or here (http://en.wikipedia.org/wiki/John_F._Kennedy_assassination#Aftermath_in_Dealey_ Plaza).
