The Muslim Army psychiatrist who allegedly opened fire on fellow soldiers at Fort Hood and killed 13 aggressively pushed Islam on his patients to the point he was disciplined over the issue, according to a report today.

Maj. Nidal Malik Hasan, 39, is suspected of opening fire with two handguns yesterday at the Texas base’s readiness center, where soldiers were getting last-minute checkups before deploying to Iraq and Afghanistan.

A source told National Public Radio‘s Joseph Shapiro that Hasan was given a period of probation early in his postgraduate work for proselytizing Islam with coworkers and soldiers he was treating.

The source was someone who worked with Hasan at the time, NPR reported.

Hasan did his early postgraduate work at the Uniformed Service University of the Health Sciences in Bethesda, Md.

Hasan reportedly is in stable condition after being shot four times by a female civilian officer, who also was wounded. He was upset about his scheduled overseas deployment, according to Sen. Kay Bailey Hutchison of Texas.

Nader Hasan, the suspect’s first cousin, told Fox News his relative was a “good” American, was born in Arlington, Va., and went to local high schools and then Virginia Tech.

The Associated Press has said authorities actually started looking into Hasan’s activities several months ago after Internet postings about suicide bombings were linked to him.

Robert Spencer at JihadWatch.org says the evidence points to a clear link between Hasan’s Muslim faith and the massacre.

“CAIR (the Council on American-Islamic Relations) has been working overtime … and the ‘Muslims fear backlash’ victimhood machine is in high gear. No one, of course, is questioning whether there might be any connection between this man’s devoutly held Islam and the massacre today. After all, how could there be any such connection? ‘Islam is a Religion of Peace,'” he wrote.

Spencer noted officials are saying, as NPR reported, “the motive behind the shootings was not immediately clear.”

“Nothing can be made clear to those who do not wish to see,” Spencer writes

A participant in a forum at JihadWatch charged the “Pentagon, the American military, the Army, those who run Fort Hood, are guilty, in their refusal to recognize the effect of Islam on the minds of men, in their willful ignorance of what is contained in Quran, Hadith, and Sira.”

The contributor said everyone in authority “in the Western world who presumes to protect and defend ‘the people,’ has a duty to learn about Islam. … Nothing but immediate, and detailed knowledge, of the texts and the tenets and the attitudes and the atmospherics of Islam, will do.”
