Denison's documentary What Happened in Vegas is more than a revenge project. He unveils a pattern of police malfeasance, including coverups and lies, through disturbing stories of unjustified deaths.
It's a damning takedown of the city's powers that be -- casinos cozy with a sheriff willing to protect their interests, and a constabulary infected with a Wild West mentality, armed with military weaponry and prone to lies. He argues that those powers even abet a law enforcement debacle surrounding the recent mass shooting at an outdoor music festival that left 58 concertgoers dead and more than 500 injured.
Denison keeps up the pace -- those television skills coming in handy -- and unpacks a lot. But he also allows in some light. There are plenty of Las Vegas police officers who want things to change, and Denison gives them, and the victims' families, a voice.
Sin City is a peculiar place, where losing money is the main tourist attraction, but the problems Denison uncovers serve as a warning to all Americans. While African-Americans, unsurprisingly, took the brunt of the police atrocities he exposes, he also shows how bad police ultimately will maltreat anyone.
