It was 10 years ago today that the high school massacre at Columbine occurred, and not surprisingly, there’s a new younger generation who know nothing about it or that it even happened.

Last week, USAToday published an article that effectively laid to rest many of the assumptions that the public was led to believe immediately following the massacre. The killers were not bullied (in fact, they were the bullies themselves), they weren’t part of the so-called “Trenchcoat Mafia”, and it wasn’t violent video games that caused them to shoot up their school.

Here’s a rather chilling detail from the article:

What’s now beyond dispute — largely from the killers’ journals, which have been released over the past few years, is this: Harris and Klebold killed 13 and wounded 24, but they had hoped to kill thousands.

The pair planned the attacks for more than a year, building 100 bombs and persuading friends to buy them guns. Just after 11 a.m. on April 20, they lugged a pair of duffel bags containing propane-tank bombs into Columbine’s crowded cafeteria and another into the kitchen, then stepped outside and waited.

Had the bombs exploded, they’d have killed virtually everyone eating lunch and brought the school’s second-story library down atop the cafeteria, police say. Armed with a pistol, a rifle and two sawed-off shotguns, the pair planned to pick off survivors fleeing the carnage.

As a last terrorist act, a pair of gasoline bombs planted in Harris’ Honda and Klebold’s BMW had been rigged apparently to kill police, rescue teams, journalists and parents who rushed to the school — long after the pair expected they would be dead.

The pair had parked the cars about 100 yards apart in the student lot. The bombs didn’t go off.

Oh, and that story of a girl getting shot point-blank in the head after responding ‘yes’ to whether or not she was a Christian…yeah, that never happened according to the FBI.
