Question: What year did Pilger last say he believed there was a second gunman?
About the article "Assassination of Robert F. Kennedy", section "Second gunman theory".

Candidate passages:
  The English writer Auberon Waugh, writing in "The Spectator" in the 1970s in response to an article Pilger had written alleging Thai complicity in child trafficking (whose research was challenged), coined the verb "to pilger", defined as: "to present information in a sensationalist manner to reach a foregone conclusion".
The word was included in the "Oxford Dictionary of New Words" in 1991, but removed from the subsequent edition after Pilger complained.
Some sources said that he threatened legal action.
Noam Chomsky responded to Waugh's neologism by stating that "pilgerize" was "invented by journalists furious about his incisive and courageous reporting, and knowing that the only response they are capable of is ridicule."
The writer William Shawcross has described him as "one of the worst journalists writing in the English language".
The Anglo-American writer Christopher Hitchens said of Pilger: "I remember thinking that his work from Vietnam was very good at the time.
I dare say if I went back and read it again I'd probably still admire quite a lot of it.
But there is a word that gets overused and can be misused – namely, anti-American – and it has to be used about him.
So that for me sort of spoils it... even when I'm inclined to agree."
"The Economist" Lexington columnist commented on Pilger's account of the Arab uprising: Praise and criticism.
Next up is the egregious John Pilger, who thinks the Arab revolts show that the West in general and the United States in particular are "fascist."
... Maybe he hasn't noticed, but what most of the Arab protesters say they want are the very freedoms that they know full well, even if Pilger doesn't, to be available in the West.
No doubt he believes they are labouring under some massive mind-control delusion engineered by the CIA. 
In 2003 and 2004, Pilger strongly criticised the policies of United States President George W. Bush, saying that he had exploited the 9/11 terrorist attacks in his 2003 invasion of Iraq and later occupation.
Pilger in 2004 criticized then British Prime Minister Tony Blair as equally responsible for the invasion and the bungled occupation of Iraq.
In 2004, as the Iraq insurgency increased, Pilger wrote that the anti-war movement should support "Iraq's anti-occupation resistance:""We cannot afford to be choosy.
While we abhor and condemn the continuing loss of innocent life in Iraq, we have no choice now but to support the resistance, for if the resistance fails, the "Bush gang" will attack another country.
"His support for the Iraqi insurgency was criticised at the time by some, including Andrew Bolt.
He described Pilger as an "apologist for terrorists".
On 25 July 2005, Pilger ascribed blame for the 2005 London bombings that month to Blair.
He wrote that Blair's decision to follow Bush helped to generate the rage that Pilger said precipitated the bombings.
In his column a year later, Pilger described Blair as a war criminal for supporting Israel's actions during the 2006 Israel–Lebanon conflict.
He said that Blair gave permission to Israeli Prime Minister Ariel Sharon in 2001 to initiate what would ultimately become Operation Defensive Shield.
Pilger criticised Barack Obama during his presidential campaign of 2008, saying that he was "a glossy Uncle Tom who would bomb Pakistan" and his theme "was the renewal of America as a dominant, avaricious bully".
After Obama was elected and took office in 2009, Pilger wrote, "In his first 100 days, Obama has excused torture, opposed "habeas corpus" and demanded more secret government".
Gerard Henderson, a conservative Australian newspaper columnist, accused Pilger later in 2009 of "engaging in hyperbole against western democracies."
Pilger was founded in 1880. 
In an interview with Best on November 19, 2008, Francesa insisted that there was no smoking gun, no juicy, untold key regarding the breakup with Russo.
However, Francesa believed a contributing factor was a fallout from Imus' firing in April 2007 because Russo wanted to pursue the morning slot alone, but the WFAN management was hesitant to break up the pairing.
Francesa sensed that Russo was disappointed.
Francesa said, "In retrospect, I think it set us off on a bad path that last year.
I don't mean that caused Dog to leave.
He left because he had an opportunity ...
But we had a very rocky last year.
I think what might have caused some of that was his feeling, stronger than I knew at the time, that he wanted to go to mornings more than I did.
"In reflection, Francesa said, "We had 20 years of something that was great.
We're linked forever.
That's just life.
So the idea that people want to paint Mike vs. Mad Dog, who's the good guy, who's the bad guy?
You know what?
There is no bad guy.
"In another interview with Jerry Barmash on June 29, 2012, regarding Russo leaving the show, Francesa said, "I didn’t begrudge him leaving for one second.
I never had an issue with that.
It just wasn’t handled properly, which I think he now understands it and would readily admit.
"Francesa said he and WFAN operations manager Mark Chernoff got word through back channels of Russo’s plan three months before it was made public.
But Russo kept quiet until the end.
Russo declined to be interviewed.
In an interview with Bob Raissman on June 30, 2012, Russo said that the decision to part ways with Francesa was the biggest one of his life, which was made by himself.
He still asked, "You think I did the right thing?
"Russo said, "It’s almost like in the last four years, it’s almost like I’ve forgotten I was at FAN for so long.
This (Sirius/XM’s "Mad Dog Radio") is a different kind of element, a different kind of show.
It’s all-consuming.
It’s so different than what I was used to," Russo said.
"You forget what you accomplished in that 20-year period.
It’s almost like I forget I was at FAN for 20 years.
"In the same interview with Raissman, Russo did not rule out a reunion with Francesa.
Russo said, "You never want to say never.
You know how the radio business is.
So, you never say never, but I haven’t thought about it in my crystal ball, let’s put it that way...
But I’ll tell you right now, if Mike and I did shows together we would have no trouble picking right up where we left off."
With others, Pilger supported Julian Assange, founder of Wikileaks, by pledging bail in December 2010.
Pilger said at the time: "There's no doubt that he is not going to abscond".
Pilger featured the Wikileaks editor-in-chief in his documentary "The War You Don't See" (2010).
Pilger described the accusations against Assange in Sweden as a "political stunt" consisting of "concocted charges", an opinion British left-wing journalist Owen Jones has implicitly criticised.
Pilger's bail money was lost in June 2012 when a judge ordered it to be forfeited.
Assange had sought to escape the jurisdiction of the English courts by entering the embassy of Ecuador.
Pilger visited Assange in the embassy and continues to support him.
