It has emerged that John Walker Lindh, the young Northern Californian
Taliban fighter captured in Afghanistan,
was
a prolific Usenet poster, frequenting groups such as
rec.music.hip-hop, and using pseudonyms including "Prof.J", "Dr. Hine E. Craque" and "Mr. Muhajid", before deciding to run away and join the Taliban.
Thanks to Google, there is a history of his posts,
dissing wack rhymes, buying and selling CDs and musical instruments (mostly
drum machines/samplers, though he was looking for a talkbox at one stage),
and apparently getting into Islam through hip-hop music.
