While 13 people were killed at Columbine by two loner nut cases, over 80 people were killed at Waco by the very organization that was created to safe guard us all, the government. The Columbine shooters would have been punished if they had been caught prior to their suicides. No one was ever punished for Waco.
My take on all of this - forget Columbine. Remember Waco.
Nor will I soon forget the two men chiefly responsible for it, Bill Clinton and Janet Reno.
