Editing Training Day (section)

===Development===
Although corruption in the LAPD's [[Community Resources Against Street Hoodlums|C.R.A.S.H.]] unit was yet to be exposed when ''Training Day'' was written, Antoine Fuqua has stated that the emergence of the [[Rampart scandal|Rampart Scandal]] in the late 1990s catalyzed the completion of the film. Denzel Washington also grew a beard in order to emulate the appearance of [[Rafael Pérez (police officer)|Rafael Pérez]], an LAPD narcotics officer involved in multiple scandals.<ref>{{cite book|title=Bad: Infamy, Darkness, Evil and Slime on Screen|author=Murray Pomerance|author-link = Murray Pomerance |publisher=SUNY Press|date=February 1, 2012}}</ref><ref>{{cite book|title=Racial Spectacles:Explorations in Media, Race and Justice|author=Jonathan Markovitz|publisher=Taylor & Francis|date=October 14, 2011}}</ref> Fuqua wanted Washington's character to be seductive and part of a machine, and not just a random rogue cop. In Washington's own words: "I think in some ways he's done his job too well. He's learned how to manipulate, how to push the line further and further, and, in the process, he's become more hard-core than some of the guys he's chasing."<ref name="Rediff">[http://www.rediff.com/entertai/2001/oct/06us.htm "Man on a mission"] {{Webarchive|url=https://web.archive.org/web/20080726200734/http://www.rediff.com/entertai/2001/oct/06us.htm |date=July 26, 2008 }}.

Fuqua also saw Ethan Hawke's character as generally honorable but so driven by ambition that he was willing to compromise his principles, particularly when following the charming and persuasive example of Washington's character. He has said that he fought with studio executives who wanted to cut the Three Wise Men scene, thinking it slowed the film. He insisted that the scene was pivotal in establishing that at least some of Alonzo's illegal actions were sanctioned by his superiors who regarded unethical behavior as a necessary evil.<ref name="DVD commentary">{{cite AV media | people=Fuqua, Antoine (director, primary contributor) | date= June 3, 2002 | title=Training Day DVD | medium=Motion picture commentary | location=U.S.}}</ref>

Fuqua wanted ''Training Day'' to look as authentic as possible, and he shot on location in some of the most infamous neighborhoods of Los Angeles. He even obtained permission to shoot in the [[Imperial Courts]] [[Public housing|housing project]], the first time L.A. street gangs had allowed a film crew to be brought into that neighborhood. The crew also filmed in Hoover Block and [[Baldwin Village, Los Angeles|Baldwin Village]].<ref name="Notes">{{cite web |title='Training Day' Production Notes |url=http://www.kingroom.com/movies/2001/training_day/notes.htm |archive-url=https://web.archive.org/web/20020122034510/http://www.kingroom.com/movies/2001/training_day/notes.htm |url-status=dead |archive-date=January 22, 2002 |work=[[Warner Bros.]] |access-date=February 11, 2010 }}</ref> Parts of the film were shot on the dead end street Palmwood Drive, where [[Black P. Stones (Jungles)|Black P. Stones]] gang members were seen on the rooftops. [[Cle Shaheed Sloan]], the gang technical advisor of ''Training Day'', managed to get on screen real-life gang members from [[Rollin 60's Neighborhood Crips|Rollin' 60 Crips]], [[Crips|PJ Watts Crips]], and Black P. Stones. According to Fuqua, the actors and crew ended up receiving a warm welcome from local residents. When he was unable to shoot a scene directly on location, he recreated the locations on sets.<ref name="DVD commentary"/>

There were also two police officers on hand as [[technical advisor]]s, Michael Patterson and Paul Lozada (the latter from the [[San Francisco Police Department]]). Washington, Hawke and other cast members also met with undercover police officers, local drug dealers, and gang members to help understand their roles better.<ref name="Notes" />
