Ronald Radosh explains in The Weekly Standard why the Rumpled Academic walked:
The acquittal on December 6 of Sami al-Arian, a former professor of computer engineering at the University of South Florida, on eight counts relating to terrorism was a setback not only for the Department of Justice and the Bush administration, but also for the struggle against Islamic extremism itself. That the Florida jury deadlocked on another nine counts, however, leaves open the possibility of his ultimate conviction.
Al-Arian was indicted in February 2003 for his involvement with Palestinian Islamic Jihad, a group that engages in terrorist acts including suicide bombings in Israel, Gaza, and the West Bank. And his trial did clarify once and for all–after years of denial by the professor and his supporters–that Al-Arian was a member of Palestinian Islamic Jihad, approved of its goals and methods, and raised money in the United States to finance its activities. Nevertheless, after five months of trial and 13 days of deliberation, the jury found Al-Arian not guilty on the most serious counts against him, including conspiracy to murder and maim abroad.
On these counts, the prosecution may have overplayed its hand. The Department of Justice built its case on nine years’ worth of secret surveillance (fully authorized under the Foreign Intelligence Surveillance Act, by the way), including almost 500,000 intercepts of faxes and phone conversations, many of them exchanges between Al-Arian and leaders of Palestinian Islamic Jihad. The terms of the Patriot Act made this evidence admissible in court. And it showed Al-Arian’s sympathies and intent beyond any doubt.
Government Exhibit T–516, for example, is a letter written by Al-Arian on February 10, 1995, to Ismail al-Shatti, a member of the Kuwaiti legislature. In the letter, Al-Arian noted that both Hamas and Islamic Jihad were “being threatened by the enemy.” Al-Arian called for “preserving the spirit and flame of Jihad against the enemy,” and went on to praise a recent suicide bombing in Israel carried out by “martyred mujahedeen” as “the best guide and witness to what the believing few can do in the face of Arab and Islamic collapse at the heels of the Zionist enemy.” Al-Arian urged al-Shatti to “extend true support of the jihad effort in Palestine so that operations such as these can continue.” He described the movement’s “very difficult” financial situation and urged Al-Shatti to explore “the feasibility of assistance from benevolent people and institutions whom you know to the jihad in Palestine.” The prosecution showed that Al-Arian spoke about the letter on the phone two days after writing it, asking a friend to “carry the message” overseas when he went abroad.
While the prosecution stressed the hideous nature of Islamic Jihad’s attacks on civilians, it did not establish a link between Al-Arian and any specific act of violence. And it failed to persuade the court that the law required no such link for a conviction. This left an opening for the defense to argue–as Al-Arian’s friends long had–that he was simply a professor persecuted for his political beliefs.
