"To effectively combat terrorism, whether international or domestic, what you need are human sources -- spies, informants," explained Hogan. "They need to penetrate into the terrorist organization on a long-term basis."

Obtaining such inside information was critical in convicting David Wayne Hull -- a self-declared Imperial Wizard of the White Knights of the Ku Klux Klan who operated a "cell" in western Chester County -- of a number of weapons charges, witness tampering and a charge of instructing others how to use a pipe bomb in furtherance of a federal crime.

Hull, 41, of Washington County, was found guilty of seven of 10 charges after a trial in May. The case was prosecuted by Assistant U.S. Attorney Margaret Picking. Hull was defended by W. Penn Hackney."
