The home videos Eric Harris and Dylan Klebold made prior to the shootings of April 20th, 1999, have captured a lot of attention. There are several that have been identified, though not all have been released. The Basement Tapes are the most notorious of the unreleased videos: They don't even stand a chance of being made public until 2026. Apart from that video, I find Hitmen for Hire one of the most intriguing because it looks, to me, almost like a dress rehearsal for what they did at Columbine High School that day.
In the gunmen's Hitmen for Hire video, the boys played the part of hitmen-for-hire, the men in black that geeks, outcasts, nerds, and other picked-on souls could turn to in order to take care of bullies who were harassing them and making their lives hell. In the film, Dylan and Eric run around protecting the weak - dressed in their trenchcoats and wearing cool sunglasses - and taking out the 'bad guys', the bullies. The video is reminiscent of Pulp Fiction but I can't help but see 4-20 in the film -- particularly since it was filmed in Columbine High.
