Al-Arian was found not guilty, but he was definitely not innocent. They had him on tape praising successful suicide bombings, etc, but couldn't come up with solid evidence that he was directly raising funds even though he was meeting with key jihadists. They were unable to get a Muslim FBI agent to record him on tape, which would have made the case airtight. As it is, they may still be able to kick him out of the country on immigration violations.
