The Fourth Amendment is treated across these episodes less as a single doctrine than as a set of procedural guarantees — warrants, individualized probable cause, judicial authorization — whose meaning is contested in policing, surveillance and constitutional interpretation.
The blurring line between cop and soldier
In an episode on Posse Comitatus, Radley Balko argued that while the United States has mostly kept the military out of domestic law enforcement, the country now has domestic police officers who look and act and are armed like soldiers. He listed the transfers: the weapons of soldiers, equipment such as tanks and armored personnel carriers and helicopters, uniforms — many departments having switched from police blues to battle dress uniforms — and training in military tactics with SWAT raids and military lingo. Balko contrasted the soldier’s job, to annihilate a foreign enemy, with the police officer’s job, to keep the peace and protect rights, and warned that treating cops as soldiers blurs that distinction, so that officers come to see their patrol areas as battlefields and the people they serve as potential enemies or threats Posse Comitatus – Repealed but Not Gone (2013).
Bob Zadek framed the change as a shift in the relationship between protector and protected: he said there was a time when he did not view the policeman as somebody to be feared, and that this core relationship has changed. Balko responded that there is a danger of romanticizing a time that may never have existed, though he allowed there probably was a time when people like Zadek did not fear the police Posse Comitatus – Repealed but Not Gone (2013).
Buying around the warrant requirement
In a 2021 episode, Liza Goitein argued that the government should not be able to purchase data that intrudes on privacy. Zadek pressed an analogy: if the government may buy binoculars it might misuse, why not data it might misuse? Goitein answered that the Supreme Court has said location information is so private that the government needs a warrant just to collect it, so the question is not how the data will be used but whether the government is buying its way around the warrant requirement that applies to getting the data at all. She distinguished binoculars: looking into a house through an open window is not considered a Fourth Amendment issue, and police may use binoculars outside to look closer at somebody who is outside, which is not a huge intrusion on a reasonable expectation of privacy New Tests for the Fourth Amendment (2021).
Goitein described the geolocation information at issue as a comprehensive record of everywhere a person has been, day in and day out, stretching back months and potentially years — a historical and ongoing record of precise whereabouts that can reveal some of the most sensitive possible information about a person. Zadek agreed with the principle and raised a parallel concern about so-called cancel culture and the misuse of publicly available data, saying the private sector also misuses data with a chilling effect. Goitein separated the two: what a person puts on social media is put there voluntarily to make it public, whereas location information is not deliberately made public; and the buyers of cell phone location data are wealthy purchasers of huge databases with the technology to run algorithms, not people waging cancellation campaigns. She said marketers and private entities with access to the data do not seem to cause a chilling effect, but that stronger legal protections against sales or disclosures to private entities are needed, because the government has coercive powers the private sector does not — the power to jail, and to launch a drone strike against an American citizen overseas — and the incentive to target people based on ideology, whereas private actors are trying to make money New Tests for the Fourth Amendment (2021).
The Fourth Amendment Is Not For Sale Act
Goitein described pending legislation called the Fourth Amendment Is Not For Sale Act, which would prohibit law enforcement and intelligence agencies — not public health or education agencies — from purchasing or exchanging for anything of value the type of information at issue, including geolocation information and communications content, and all the things telephone companies are currently not allowed to sell to the government. She said it also prohibits those agencies from sharing the data with law enforcement and intelligence agencies. Asked where it falls short, she said it does not prohibit voluntary disclosures without payment: a company might give information to the government gratis to curry favor for a contract, to avoid regulation, or to get on the government’s good side, so the law should make clear that disclosure of this kind of personal data under any circumstances requires a court order and legal process New Tests for the Fourth Amendment (2021).
Theory of warrants and the raid on U.S. Private Vaults
In a 2023 episode, Zadek asked Mike Greenberg to set out the theory of the process the founders set up in the Fourth Amendment, enacted in 1791, before there is an invasion of privacy protected by the amendment. Greenberg said that in theory your property is your castle and the government cannot search or invade your property or privacy without a judicially authorized warrant supported by individualized probable cause that you have done something wrong or that evidence of something wrong is on your property — and that the warrant must be issued by a judicial officer. Zadek characterized this as the system of checks and balances: a judge sworn to enforce and defend the Constitution must be persuaded that there is reason to single out a particular house and property before police may kick down the door and seize property; the police cannot act merely because they do not like you Civil Asset Forfeiture Revisited (2023).
Greenberg said the principle at stake in his case was that the government should not get to rifle through people’s things without individualized probable cause. He illustrated it with an apartment building: reason to think someone is conducting a drug sale out of the main office does not give the government license to search and seize the contents of every apartment despite not thinking anybody in any particular apartment did anything wrong. He said the case was being pressed to get a court to declare that conducting a criminal search when the warrant specifically said they could not, and misleading a magistrate, violates the Fourth Amendment Civil Asset Forfeiture Revisited (2023).
On the facts, Greenberg said the raid was in March 2021 and the last of his clients did not get their things back until around October, with people he did not represent still trying to recover their property. He recounted accompanying two clients to the FBI office in Los Angeles to receive their belongings — grocery bags filled with precious metals — and the two agents facilitating the return asking whether they would like to be accompanied to the car because there were homeless people in the area and they would not want them to get robbed. Greenberg said civil forfeiture turns the police into robbers Civil Asset Forfeiture Revisited (2023).
He said the government kept records — notes of documents and heirlooms, debit and credit cards held up to a camera — and that the litigation continued to seek a declaration that going into the boxes at all and lying to the magistrate judge violated the Fourth Amendment, and an order that the government destroy the records it wrongfully created. The court issued an initial ruling saying that although there was evidence the government was trying to conduct a criminal search the warrant prohibited — two drug-sniffing dogs, a form unconcerned with inventorying the actual contents — what the government did was close enough to an inventory search, so no Fourth Amendment violation. Greenberg called the ruling confounding and said the case was being appealed to the Ninth Circuit, with an opening brief due the following month. He framed the stakes as every American’s constitutional rights: if the government can search one place it has probable cause for and use it as a pretext to search other places it does not, that opens the door to law enforcement malfeasance that would make everybody less secure in their property Civil Asset Forfeiture Revisited (2023).
Judicial declaration of rights
In an episode on the Supreme Court, David Kaplan said his book is heavily critical of Roe v. Wade, that his own politics are decidedly left of center, and that as a legislator he would support extremely liberal, unrestrictive abortion laws — but that he does not think those rights ought to be declared by judges and does not think it is a constitutional matter. He said not all intelligent, wise policy derives from the Constitution, and that the Court ought not be in the business of determining the — the excerpt breaks off there Demystifying the Supreme Court (2019).
Across episodes
The excerpts show no single developing argument across the four episodes. The 2013 episode treats militarized policing and the protector-protected relationship; the 2019 episode treats judicial declaration of rights; the 2021 episode treats the warrant requirement as a bar to government purchase of geolocation data and the Fourth Amendment Is Not For Sale Act; and the 2023 episode treats the theory of individualized probable cause and its breakdown in the U.S. Private Vaults raid and Ninth Circuit appeal. Different guests advance each treatment, and no guest reappears.
What the sources do not cover
The excerpts do not state the holding of any Supreme Court case by name, the text of the Fourth Amendment, or the outcome of the Ninth Circuit appeal. They do not give the status of the Fourth Amendment Is Not For Sale Act beyond its description as pending legislation, nor the fate of the district court ruling Greenberg was appealing. The Kaplan excerpt breaks off mid-sentence, and the 2023 episode’s second excerpt ends with a speaker label and no content.
