Use Primary Source Finder to investigate four focused record groups: the 2001 AUMF, USA PATRIOT Act, Homeland Security Act, and 9/11 Commission records. I built this page to help you find the official text, test a specific claim, and keep a clear note of what each record can and cannot prove.
Search a specific claim, find the record, fact-check it, ask Sofia, and save the source trail.

Quick answer
The three public laws show what Congress authorized or reorganized. The 9/11 Commission records show the official investigation, testimony, findings, and recommendations. Together they support a focused inquiry into federal legal and institutional change, not every consequence of 9/11.
Public Law 107-40 records the force Congress authorized after the attacks.
What it helps prove
The enacted scope and wording of the post-attack authorization.
What it cannot prove
Not whether every later operation fit the resolution or other law.
Public Law 107-56 changed federal investigative, surveillance, financial, immigration, and information-sharing rules.
What it helps prove
What Congress enacted in October 2001, section by section.
What it cannot prove
Not how every authority was used or whether a specific person was surveilled.
Public Law 107-296 established DHS and reorganized federal functions.
What it helps prove
The department's legal creation, missions, structure, and transferred functions.
What it cannot prove
Not the effect or legality of every later DHS policy.
The final report, public hearings, released interview memoranda, and commission files document the government's official investigation.
What it helps prove
What the commission concluded and recommended, what witnesses told it, and the structure of its evidentiary trail.
What it cannot prove
The final report is primary evidence of the commission's conclusions but an official secondary synthesis for reconstructing the attacks; follow it to underlying records.
Search prompts
Supporting evidence
These sources matter when the question moves from federal law and government records to experience, memory, place, or public communication. I would use them as supporting evidence, not as substitutes for the statutes or commission files.
These records add lived experience, memory, responder work, and personal perspective that statutes cannot capture.
Boundary: They do not establish enacted law, legislative intent, or events beyond a witness's position.
These records add visible conditions, place, sequence, public response, and what institutions communicated at the time.
Boundary: They do not by themselves prove motive, legal authority, or facts outside the captured frame or page.
FAQ
Start with Public Law 107-40 for post-attack war powers, Public Law 107-56 for changes to investigative and related federal authority, and Public Law 107-296 for the creation and structure of the Department of Homeland Security. Use the 9/11 Commission report, hearings, and released records to investigate the official inquiry and its evidence trail.
It is primary evidence for what the commission concluded and recommended, but it functions as an official secondary synthesis when reconstructing the attacks. For a specific factual claim, follow its notes to testimony, exhibits, agency records, and other underlying evidence where possible.
Yes. Public Law 107-56 is the enacted primary source for what Congress changed in October 2001. It does not by itself prove how every authority was later interpreted or used.
Public Law 107-40 proves the wording and scope of the force Congress authorized after the attacks. It does not by itself settle whether every later military operation fit that authorization, the Constitution, or international law.
Public Law 107-296 proves how Congress legally established the Department of Homeland Security, defined its missions and structure, and transferred federal functions. It does not prove the effect, effectiveness, or legality of every later DHS policy.
