Immigration is the font of so-called domestic terrorism. Almost all of those arrested for terrorism in the United States since 2009 were aliens of some sort or another:
Rice University November 15, 2011
Sixty percent of people arrested for Islamic terrorist activities between January 2009 and April 2011 were American citizens, according to a new report from Rice University's Baker Institute for Public Policy. The study of 104 people who were arrested included U.S. and non-U.S. citizens living in America or abroad...
"Providing policymakers this data can allow for a factual discussion and diminish rhetoric," Neuhaus Schaan said. "Consequently, policy can be crafted to address current and future needs in the face of change and adaptation by those determined to bring harm to the United States."
Other key findings from the report include:
Of the 104 people arrested for Islamic extremist activities between January 2009 and April 2011, half were born in the U.S., 22 percent were naturalized citizens and 7 percent were dual citizens.
Of the 104, 5 percent entered the U.S. on a visa. Sixty-three percent of converts had a known prior criminal record.
Of the 14 American converts with a prior criminal history, at least 55 percent had converted to Islam in prison.
Ninety-two 92 percent were male. Sixty-four percent were 30 years old or younger.
Sixty-six percent had traveled or were in the process of traveling to the Middle East, Somalia, South Asia or the Balkans.
Of the 104, 70 percent had an association or were attempting an association with an internationally recognized terrorist organization; al-Qaida and its associated branches were cited most.
Of the 29 persons with no known association to a group, 11 had been active on terrorist-related chat rooms and websites.
Overall, 38 percent had been involved in this Internet activity.
Only 10 of the 104 are what the authors would consider "lone wolves"; most in the cohort had ties to others in the group or to an organization.
However, despite the misleading headline, the Muslim terrorism problem is an alien and immigration problem:
“Information on birthplaces and conversion to Islam was available for 77 of the 104 people arrested. The data revealed that 60 percent of the group was born outside the U.S. Of the 31 U.S.-born persons where religion of origin could be determined , 14 were born into Muslim families and 17 converted to Islam. “
And it is most likely that those born into a Muslim family in the United States are the descendants of immigrants. That makes at a minimum 60 of the 104 terrorists were born outside the United States or are presumably first generation Americans. This tells us that ending Muslim immigration will severely reduce Muslim terrorism in the United States. It is that easy. It also tells us that our naturalization process is not weeding out terrorists, terrorist sympathizers, or those prone to become terrorists. So much for the much vaunted "background checks" that U.S. Citizenship and Immigration Services does.
