Bowling for Columbine (2002)

Political documentary filmmaker Michael Moore explores the circumstances that lead to the 1999 Columbine High School massacre and, more broadly, the proliferation of guns and the high homicide rate in America. In his trademark provocative fashion, Moore accosts Kmart corporate employees and pleads with them to stop selling bullets, investigates why Canada doesn't have the same excessive rate of gun violence and questions actor Charlton Heston on his support of the National Rifle Association.
