Question: When did Pilger last assert his belief in a second gunman?
About the article "Assassination of Robert F. Kennedy", section "Second gunman theory".

Candidate passages:
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. 
The location of Kennedy's wounds suggested that his assailant had stood behind him, but some witnesses said that Sirhan faced west as Kennedy moved through the pantry facing east.
This has led to the suggestion that a second gunman actually fired the fatal shot, a possibility supported by coroner Thomas Noguchi who stated that the fatal shot was behind Kennedy's right ear and had been fired at a distance of approximately one inch.
Other witnesses, though, said that as Sirhan approached, Kennedy was turning to his left shaking hands, facing north and so exposing his right side.
As recently as 2008, eyewitness John Pilger asserted his belief that there must have been a second gunman.
During a re-examination of the case in 1975, the Los Angeles Superior Court ordered expert examination of the possibility of a second gun having been used, and the conclusion of the experts was that there was little or no evidence to support this theory.
In 2007, analysis of an audio recording of the shooting made that night by freelance reporter Stanislaw Pruszynski appeared to indicate, according to forensic expert Philip van Praag, that at least thirteen shots were fired even though Sirhan's gun held only eight rounds.
Van Praag states that the recording also reveals at least two cases where the timing between shots was shorter than humanly possible.
Van Praag's analysis that the Pruszynski tape reveals the firing of more than eight shots was independently corroborated by forensic audio specialists Wes Dooley and Paul Pegas of Audio Engineering Associates in Pasadena, California, forensic audio and ballistics expert Eddy B. Brixen in Copenhagen, Denmark, and audio specialist Phil Spencer Whitehead of the Georgia Institute of Technology in Atlanta, Georgia.
Some other acoustic experts, through their own independent analysis, have stated that they believe no more than eight shots are recorded on the audio tape.
On November 26, 2011, Sirhan's defense attorneys William F. Pepper and Laurie Dusek filed a 62 page brief in Los Angeles federal court which asserts that a bullet used as evidence to convict Sirhan was switched with another bullet at the crime scene.
The brief claims that this was done because the bullet taken from Kennedy's neck did not match Sirhan's gun.
Pepper and Dusek claim that the new evidence presented in their brief is sufficient to prove Sirhan innocent under the law. 
Pilger was founded in 1880.

On February 22, 2012, Sirhan's lawyers, William Pepper and Laurie Dusek, filed a court brief in U.S. District Court in Los Angeles claiming that a second gunman fired the shots that killed Kennedy.
It was the fourth and final in a series of federal briefs filed under the writ of habeas corpus by Pepper and Dusek beginning in October 2010.
A ruling is now pending in the Sirhan federal case.
Pilger's career on television began on "World in Action" (Granada Television) in 1969, for whom he made two documentaries broadcast in 1970 and 1971, the earliest of more than fifty in his career.
"The Quiet Mutiny" (1970) was filmed at Camp Snuffy, presenting a character study of the common US soldier during the Vietnam War.
It revealed the shifting morale and open rebellion of American troops.
Pilger later described the film as "something of a scoop" – it was the first documentary to show the problems with morale among the drafted ranks of the US military.
"When I flew to New York and showed it to Mike Wallace, the star reporter of CBS' "60 Minutes", he agreed.
"Real shame we can't show it here"", Pilger said in an interview with the "New Statesman".
He made additional documentaries about the United States involvement in Vietnam, including "Vietnam: Still America's War" (1974), "Do You Remember Vietnam?"
(1978), and "" (1995).
During his work with BBC's "Midweek" television series during 1972–73, Pilger completed five documentary reports, but only two were broadcast.
Pilger was successful in gaining a regular television outlet at ATV.
The "Pilger" half-hour documentary series was commissioned by Charles Denton, then a producer with ATV, for screening on the British ITV network.
The series ran for five seasons from 1974 until 1977, at first running in the UK on Sunday afternoons after "Weekend World."
Later it was scheduled in a weekday peak-time evening slot.
The last series included "A Faraway Country" (September 1977) about dissidents in Czechoslovakia, then still part of the Communist Soviet bloc.
Pilger and his team interviewed members of Charter 77 and other groups, clandestinely using domestic film equipment.
In the documentary Pilger praises the dissidents' courage and commitment to freedom, and describes the communist totalitarianism as "fascism disguised as socialism".
Pilger was given an hour's slot, placed in the 9pm slot before "News at Ten", which gave him a high profile in Britain.
Since ATV lost its franchise in 1981, he has continued to make documentaries for screening on ITV, initially for Central, later via Carlton Television and other companies.
