Dear Mr. Huffman,

Thank you for the question about the ACLU's position on the Second Amendment. The national ACLU is neutral on the issue of gun control.

We believe that the Constitution contains no barriers to reasonable regulations of gun ownership. If we can license and register cars, we can license and register guns. The question therefore is not whether to restrict arms ownership, but how much to restrict it. If that is a question left open by the Constitution, then it is a question for Congress to decide.

You can find more about the ACLU's positions at http://www.aclu.org

If you are not already an ACLU member, we encourage you to help support our aggressive work on the issues you care about. To join please visit http://www.aclu.org/contribute/contribute.cfm or call 1-888-567-ACLU.

Sincerely,

D. Barber
Correspondence Manager, American Civil Liberties Union

I had already read your web page on the topic.  My suggestion was that due to new information from constitutional scholars, which I provided references to in my email, it was time for you to reevaluate your position.

Cars are not constitutionally protected as are 'arms'.

I will not be supporting the ACLU on any issue until the ACLU also defends the right to keep and bear arms issue--by far the most important issue in the Bill of Rights because it is only through the 2nd Amendment that the other rights can ultimately be guaranteed.
