Among the lesser-known holes in the Constitution cut by the Patriot Act of 2001 was the destruction of the “wall” between federal law enforcement and federal spies. The wall was erected in the Foreign Intelligence Surveillance Act of 1978, which statutorily limited all federal domestic spying to that which was authorized by the Foreign Intelligence Surveillance Court.

The wall was intended to prevent law enforcement from accessing and using data gathered by America’s domestic spying agencies.

What is lawful domestic spying?

The modern Supreme Court has made it clear that domestic spying is a “search” and the acquisition of data from a search is a “seizure” within the meaning of the Fourth Amendment. That amendment requires a warrant issued by a judge based on probable cause of crime presented under oath to the judge for a search or seizure to be lawful. The amendment also requires that all search warrants specifically describe the place to be searched and the person or thing to be seized.

The language in the Fourth Amendment is the most precise in the Constitution because of the colonial experiences with British general warrants. A general warrant was issued to British agents by a secret court in London and did not require probable cause, only “governmental needs.” That, of course, was no standard whatsoever, as whatever the government wants it will claim that it needs.

General warrants did not specify what was to be searched or seized. Rather, they authorized the bearers to search wherever they wished and to seize whatever they found — stated differently, to engage in fishing expeditions.

When Congress learned of Nixon’s excesses, it enacted FISA, which required that all domestic spying be authorized by the new and secret FISA Court. Congress then lowered the probable cause of crime standard for the FISA Court to probable cause of being a foreign agent, and it permitted the FISA Court to issue general warrants.

How can Congress, which is itself a creature of the Constitution, change standards established by the Constitution? It cannot legally or constitutionally do so. But it did so nevertheless.

Yet, the FISA compromise that was engineered in order to attract congressional votes was the wall. The wall consisted of language reflecting that whatever data was acquired from surveillance conducted pursuant to a FISA warrant could not be shared with law enforcement.

The purpose of the wall was not to protect foreign agents from domestic criminal prosecutions; it was to prevent American law enforcement from violating personal privacy by spying on Americans without search warrants.

Fast forward to the weeks after 9/11 when, with no serious debate, Congress enacted the Patriot Act. In addition to permitting one federal agent to authorize another to search private records — contrary to the Fourth Amendment — it also removed the wall between law enforcement and spying.

The FBI admission that it uses the CIA and the NSA to spy for it came in the form of a 906-page FBI rulebook written during the first Trump administration, disseminated to federal agents in 2021, and made known to Congress in 2024.

The NSA is required to go to the FISA Court when it wants to spy. We know that this, too, is a charade, as the NSA regularly captures every keystroke engaged on every mobile device and desktop computer in the U.S., 24/7, without warrants.

What is startling is that the Trump FBI actually reduced to writing its contempt for the Constitution that its employees have sworn to uphold, and the Biden FBI acted as if nothing was wrong, and under the second Trump administration, nothing has changed.

The FBI works for the Department of Justice. The CIA and the NSA work directly for the president. With a phone call, President Donald Trump — who was personally victimized by this domestic spying 10 years ago — can stop all domestic spying without search warrants. He can re-erect the wall between spying and law enforcement. He can forbid executive branch personnel from engaging with the FISA Court.

Trump can close the holes in the Constitution if he didn’t fear the wrath of an intelligence community still out of control.
