The Philadelphia-area woman who dubbed herself ''Jihad Jane'' pleaded not guilty Thursday in federal court to a four-count indictment charging her in an overseas terrorist plot. Authorities say she grew acquainted online with violent co-conspirators from around the world. They say she posted a YouTube video in 2008 saying she was ''desperate to do something'' to ease the suffering of Muslims. ''In my view, she sort of slipped sideways into Islam….There may have been some seduction into it, by one or more people,'' said Temple psychologist Frank Farley.
