Political activist/antagonist, Michael Moore (also author of 'Stupid White Men') takes a 'bemused and bitter' look at the gun laws in the US. The title springs from two fatal shootings in the town of Columbine: the first and most notorious being the mass shooting of pupils at Columbine High by two of its pupils in 1999; and the second being another fatal shooting two years later at the bowling alley of the town (which the two students had attended before they went on their killing spree in 1999). Hence the title. Moore confronts supermarket chains, the media and even pro-gun lobbyist and actor Charlton Heston (as President of the National Rifle Association).
