I agree they weren't the best parents, but to say that because they weren't attentive enough resulted in these two evil people gunning down the 13 at Columbine is straining quite a bit IMO.
Sometimes kids are bad despite everything the parents do. I just think the parents of the Columbine kids waiting around for an apology from the Klebolds and the Harrises should grab a hanky and get over it already. Bad stuff happens to good people.
Notice that Rachel Scott's father isn't doing any of this nonsense.
No apology, but I think their denial of any responsibility is ludicrous.
