Bible Denied to Guantanamo Inmate

It appears that while every inmate is given a copy of the Quran in Guantanamo Bay, the same consideration is not given to those inmates requesting Bibles. Is this a case of discrimination, or a reasonable restriction?

Saifullah Paracha, a 58-year-old former Pakistani businessmen with reputed ties to al-Qaida leader Osama bin Laden, has been in U.S. custody since 2003. Like the other inmates at Guantanamo, he has a copy of the Quran. But he also wants an English translation of the King James Version of the Bible.
Paracha believes that because the Bible is one of the scriptures accepted in Islam, he is entitled to a copy to read in his small wire-mesh cell. But after his lawyer shipped him a Bible, along with two volumes of Shakespeare, prison officials confiscated the package.
Paracha's American lawyer filed suit in U.S. District Court in Washington, demanding that Paracha be given the Bible and copies of Hamlet and Julius Caesar. The government responded that certain books are kept from prisoners because they could "incite" them.
