"I take seven kids from columbine, stand'em all in line, add an ak-47 a revolver, a nine, a mac-11 and it'll solve a problem of mine and that's a whole school of bully's shot up all at one time."

So this lyric is notable, not just for being edgy, but also because it was a product of it's time. It was published during the height of tipper gore and hillary clinton trying to appease the "moral majority" by attempting to censor rap music which is called out in the album.

Ultimately the lyric is self-censored because while the artist could have gotten away with it, the label was playing it safe, even though nothing about the lyric would have tripped the moral panic alarm. After all the rapper was white referencing a white event.
