San Jose, Calif. ? About 10,000 copies of a book about John Walker Lindh’s road to a Taliban training camp are now on the market.

The books were shipped to retailers Monday, despite a written warning to University Press, California, from a member of Lindh’s defense team alleging the book contained defamatory material.

Lindh attorney George Harris had warned in his letter, sent March 12 in response to promotional descriptions of the book, that “publication would be at your peril.”

The letter contended “the book is grossly and outrageously false and defamatory,” but did not provide specifics.
