Of what I read (somewhere) that this episode (if it wasn't banned) would have aired in October 1998. In other words, over 6 months before the incident at Columbine. But I guess people were fear-stricken back then and once the incident happened 6 months later, people made sure that this episode wouldn't air in the U.S. as people grew more paranoid after Columbine. But then again, who could blame them?
