Ref H.R. 1955 (S. 1959)

the Violent Radicalization and Homegrown Terrorism Prevention Act of 2007, written about here and here. I'd written to Sen. Coburn about this, and got a response a couple of days ago. I'll excerpt a couple of bits:
...However, I do have a few concerns with the bill that I would like to share. First, it provides for the creation of a National Commission on the Prevention of Violent Radicalization and Ideological Based Violence. This may be well-intentioned but it also is duplicative of several other functions of the government to combat domestic terror and the spread of violent ideologies. For example, the FBI and the national intelligence community already have units dedicated to the same function this bill seeks to perform.

This legislation also would establish a Center for Excellence for the Study of Violent Radicalization and Home-Grown Terrorism in the United States. This also is a well-intentioned but duplicative task given to the Department of Homeland Security. The bill calls for this Center of Excellence to survey plans of other countries and to learn from how they built their domestic radicalization programs. Quite frankly, I don't feel comfortable with our country adapting our domestic terror policies to emulate other countries around the world, as most have performed terribly in preventing the radicalization of their populace. The current struggle between secular old Europe and radical new Europe - dominated by restless Muslim immigrants and their children - is not a situation we want to duplicate here.
...
...This bill aims to scrutinize people engaging in behavior and sympathies that could eventually lead to violence instead of persons actually engaging in acts of violence. This is a nebulous and vague power that we should be very hesitant to hand to the federal government. The only real check this bill provides to protect the constitutional rights of Americans is an "audit" mandate, which would conceivably only uncover abuses of civil liberties long after they had happened. In my view, that is too late.

This is one of the reasons I'm glad I voted for him.
