UPDATE (July 16, 2008): Melanie Kroll has been active in the comments at Greg Laden's blog, where she claims she was not connected to her company VPN when the email was sent. This is patently false, since otherwise her computer would not have been able to send the email through the company mail server from an RFC 1918 private IP address, which it did. It seems that she, like her husband, is incapable of taking responsibility for her own errors. She also writes this, by way of explanation for husband's behavior:
My husband went on to the drudge report site that he reads and clicked on a link and came across that man pz's notice and responded as he always does when he is upset. Was his text extreme yes it was, would he follow through, never.So he always sends email to the authors of people who write things that make him upset, threatening to beat their brains in if they don't quit their jobs by the end of the month? That sounds like a very serious personal problem.
