In this probing documentary from director Nick Broomfield, the notoriously abrasive Englishman conducts his own investigation of two separate drive-by shootings that took the lives of rappers Biggie Smalls and Tupac Shakur in the late 1990s. Starting with the original police investigations, Broomfield attempts to knit together pieces of information while establishing the framework of the Los Angeles gangsta rap scene. He also presents home video footage of the rappers before they became household names. But it's when Broomfield tracks down former LAPD officer Russell Poole that the conspiracy theory begins to emerge. Poole has been working incessantly to expose corruption within the Los Angeles Police Department, collecting evidence that connects off-duty police officers to the murders of both rappers. Also targeted is Death Row Records head honcho Marion "Suge" Knight, whose well-documented criminal tactics lead Broomfield to implicate Knight as a key figure in both murders. A brief interview with Knight in prison proves futile, leaving Broomfield with an endless supply of questions but no concrete answers. In true Broomfield fashion, BIGGIE AND TUPAC comes off more as an entertaining shockumentary than a serious work of cinematic journalism, but it is this tone that makes it virtually impossible to dismiss.
