Violent Radicalization and Homegrown Terrorism Prevention Act of 2007

Violent Radicalization and Homegrown Terrorism Prevention Act of 2007 - Amends the Homeland Security Act of 2002 to add a new section concerning the prevention of violent radicalization and homegrown terrorism.

Establishes within the legislative branch the National Commission on the Prevention of Violent Radicalization and Homegrown Terrorism to: (1) examine and report on facts and causes of violent radicalization, homegrown terrorism, and ideologically based violence in the United States; (2) survey methodologies implemented by foreign nations to prevent such radicalization and terrorism; and (3) build upon, bring together, and avoid unnecessary duplication of related work done by other entities toward such goal.

Directs the Secretary of Homeland Security to establish or designate a university-based Center of Excellence for the Study of Violent Radicalization and Homegrown Terrorism in the United States to assist federal, state, local, and tribal government homeland security officials in preventing violent radicalization and homegrown terrorism in the United States. Requires the Secretary to ensure that activities to prevent ideologically based violence and homegrown terrorism do not violate the constitutional rights, civil rights, and civil liberties of U.S. citizens and lawful permanent residents.
