A petition was launched on WhiteHouse.gov's new We the People service on September 28, 2011: https://wwws.whitehouse.gov/petitions/!/petition/launch-real-public-subpoena-empowered-criminal-investigation-events-sept-11-2001/w9XBvTJY.

The text of the petition is:

"Launch a real, public, subpoena-empowered, criminal investigation of the events of Sept. 11, 2001.

Since the morning of Sept. 11, 2001, the United States has been a very different place. A public that grew up on a healthy diet of skepticism and independence suddenly fell in line with an administration intent on achieving its own goals by whatever means.

As part of that falling in line, we accepted a series of questionable reports from government bodies attempting to explain the details of the attacks. Experts in dozens of relevant fields have since come forward to examine the evidence more thoroughly. Their work has amounted to an unofficial investigation of the events, and many of their findings are in direct conflict with the official reports.

We should not fear the truth of anything. We need clear, straight answers taken under oath and on the public record. Investigate nine-eleven!"
