This is Part 4 (of 4) of our interview with author Dave Cullen, whose NY Times bestselling non-fiction book 'Columbine' takes a look at the 1999 school shooting. This interview was conducted at Dave Cullen's house in Denver, CO by ChuckPalahniuk.net's Kasey Carpenter.
NOTE ON VIDEO/AUDIO: This was shot on Dave Cullen's flip camera. So there is only the one angle and the sound quality is not that stellar. Also, a few of the clips cut out suddenly in the end, but the bulk of the piece if still intact.
