Interscope had previously been blamed for releasing gangsta rap albums by rappers such as Dr. Dre, Tupac Shakur, and Snoop Dogg that were deemed objectionable. Reznor called Tucker (who erroneously referred to Nine Inch Nails as a gangsta rap act) "such a fucking idiot", and claimed that the song was actually a satire of the gangsta rap genre as a whole and was originally about madness. Reznor conceded "The Downward Spiral" could be "harmful, through implying and subliminally suggesting things", whereas hardcore hip hop could be "cartoonish". Robert Bork also repeatedly referenced "Big Man with a Gun" in his book "Slouching Toward Gomorrah" as evidence of a cultural decline. The book also incorrectly states that it is a rap song. Before the Columbine High School massacre, perpetrator Dylan Klebold referenced lyrics from Nine Inch Nails songs multiple times in his journal. Klebold heavily identified with the protagonist of "The Downward Spiral" as a symbol of his own depression. On May 4, 1999, a hearing on the marketing and distribution practices of violent content to minors by the television, music, film, and video game industries was conducted before the United States Senate Committee on Commerce, Science and Transportation. The committee heard testimony from cultural observers, professors, and mental health professionals, that included conservative William Bennett and the Archbishop of Denver, Reverend Charles J. Chaput. Participants criticized the album, Nine Inch Nails' label-mate Marilyn Manson, and the 1999 film "The Matrix" for their alleged contribution to the environment that made tragedies like Columbine possible. The committee requested that the Federal Trade Commission and the United States Department of Justice investigate the entertainment industry's marketing practices to minors. In 2009, Apple rejected a proposal for a Nine Inch Nails iPhone application, citing objectionable content in the title track. Days later, Apple reversed the decision, but refused to explain its reasoning. Notes  To mark the album's tenth anniversary, "The Downward Spiral" was re-released on November 23, 2004 in high-resolution SACD and DualDisc formats. Disc one of the album's deluxe edition re-release is nearly identical to the original version; track anomalies such as sounds from previous tracks creeping up on start of tracks are fixed, and it includes a stereo and multi-channel SACD layer. The second bonus disc is a collection of remixes and B-sides and also includes a stereo SACD layer in addition to the Redbook CD layer.
