was appalled at Manson's interpretation of the song. He also found it disturbing that Manson came to define the long-haired hippie type in the public's eyes, after the prosecution's case had resulted in widespread condemnation of rock music and the idealism associated with the late 1960s hippie movement. In his 1974 book Helter Skelter, Bugliosi says he was denied permission to quote from the lyrics of "Piggies" in the book, yet not so for relevant Lennon–McCartney songs, such as "Helter Skelter", "Revolution 1" and "Blackbird". The connection between Manson's interpretation of the White Album songs and the August 1969 murders was introduced by Bugliosi in Manson's trial. Mike McGann, the lead police investigator on the Tate-LaBianca murders later stated: "Everything in Vince Bugliosi's book is wrong. I was the lead investigator on the case. Bugliosi didn't solve it. Nobody trusted him." Police detective Charlie Guenther, who investigated the murders, and Bugliosi's co-prosecutor Aaron Stovits have also discredited this as the motive for the murders. Retrospective assessment and legacy Writing in 1977, Nicholas Schaffner said that, despite the "merciless stereotypes" presented in its lyrics, "Piggies" and Harrison's three other White Album compositions "firmly established him as a contender" beside the Beatles' principal songwriters, Lennon and McCartney. Four years later, Philip Norman described the song as "mordantly humorous". Among more recent Beatles biographers, Ian MacDonald views "Piggies" as a "bludgeoning satire on straight society", dismissing it as "dreadful" and "an embarrassing blot on [Harrison's] discography". According to author Doyle Greene, writing in his 2016 book on the 1960s counterculture, the Beatles and Manson are "permanently connected in pop-culture consciousness" as a result of Manson having founded his theory of race war on McCartney's "Helter Skelter", "Piggies" and other tracks from the 1968 double album. In his book Revolution: The Making of the Beatles' White Album, David Quantick recognises the song's musical qualities – describing it as "a powerful song, full of angry climaxes" with "a fine [vocal] performance ... [and] a charming baroque feel" – yet he bemoans its "arrogant" and misanthropic message. Quantick concludes: "Although the Beatles preached peace and love and meant it, large parts of the White Album indicate that they could be a bit selective about it." Ian Inglis considers that the intentions behind Harrison's send-up of capitalist consumerism were reasonable, and acknowledges the sinister connotations that the song gained through Manson. He says that the track fails,
