The government has a legitimate duty to investigate money laundering, fraud, terrorism financing, and other financial crimes. Financial institutions also have a legitimate duty to know their customers, monitor transactions, keep required records, and report activity that meets legal thresholds.
I believe in those duties. I have spent years building a regulated financial technology company in an industry where compliance is not optional. Crypto Dispensers has had to develop an anti-money laundering program, verify customers, monitor transactions, file required reports, work with attorneys and outside compliance professionals, and respond to institutions that often regarded every cryptocurrency business as suspicious before examining how it actually operated.
That experience taught me why financial oversight matters. It also taught me why oversight needs limits.
Financial surveillance crosses the line when the government stops using data to investigate specific evidence and starts using the existence of data as a substitute for evidence. It crosses the line when every customer becomes a potential suspect, every unusual transaction becomes proof of intent, and every imperfect compliance decision is reconstructed as criminal purpose. It crosses the line when investigators remove words from their context, ignore facts that weaken their theory, or create the conditions they later cite as evidence of guilt.
The question is not whether the government should be allowed to investigate financial crime. It should. The question is whether the methods used to obtain a conviction remain consistent with the rights the government exists to protect.
If those rights disappear whenever the allegation is serious, they are not rights. They are permissions that last only until the government decides otherwise.
SECTION 01
A financial record is not a confession
Modern financial life produces an extraordinary record of human activity. A transaction can reveal where a person was, whom they supported, what medical care they sought, which political causes they funded, which religious institutions they attended, and when their family was in trouble. A complete financial history is not merely a spreadsheet. It is a detailed account of a life.
The Bank Secrecy Act requires financial institutions and other covered businesses to create and report large amounts of transaction information. Currency Transaction Reports document qualifying cash transactions. Suspicious Activity Reports alert the government to conduct that may require further review. These tools can produce valuable leads, and FinCEN describes Bank Secrecy Act data as an important resource for detecting financial crime.
But a lead is not a verdict.
A Suspicious Activity Report does not establish that a crime occurred. A large cash transaction is not inherently unlawful. A customer falling victim to a scam does not automatically make the company processing that customer's purchase part of the scam. A transaction pattern may justify a question without answering it.
This distinction matters because financial data often looks more definitive than it is. Numbers create an appearance of objectivity. A date, dollar amount, wallet address, or bank record feels concrete. Yet the meaning assigned to that record still depends on context, knowledge, and intent.
Two identical transactions can represent entirely different conduct. One may involve a customer purchasing an asset for a lawful purpose. Another may involve a person acting under the direction of a criminal. The transaction alone does not reveal what the service provider knew, what the customer had been told, or whether an unrelated third party was deceiving someone outside the provider's view.
Financial surveillance becomes dangerous when the government treats access to records as access to a person's mind.
SECTION 02
When red flags become a story
An anti-money laundering red flag is a reason to ask a question. It is not an answer, and it is not an element of a crime.
Consider a lawful cash-intensive business. It may receive cash throughout the day, deposit cash frequently, move funds between operating accounts, and pay vendors in amounts that look unusual to someone who does not understand the business. A company with overseas developers, contractors, call centers, or suppliers may regularly send international wires. A growing startup may change banks, processors, consultants, and monitoring tools as its volume increases. Its records and controls may become more sophisticated over time because the company is learning, earning more, and investing in better systems.
Each fact has an ordinary explanation. None is inherently proof of money laundering. Even repeated cash activity does not, by itself, establish illegal structuring. The question is not simply whether multiple deposits occurred, but whether someone acted with the purpose the law requires.
The danger begins when investigators count indicators instead of testing explanations. Cash deposits are described as possible structuring. Overseas payroll is called movement of funds to foreign accounts. A change in banking relationships is characterized as evasion. Improvements to a compliance program are recast as evidence that the earlier program was a sham. The labels accumulate until they appear to confirm one another.
Then the reasoning turns backward. There are many red flags, so the person must be doing something wrong. Because the person must be doing something wrong, every transaction, message, mistake, and business decision becomes another red flag.
That is not proof. It is a narrative assembled from suspicion.
Risk indicators have value when they help trained professionals decide what deserves a closer look. They become dangerous when their number is treated as a substitute for evidence of knowledge and intent. Ten ambiguous facts do not become conclusive merely because they appear on the same slide.
An honest inquiry must test innocent explanations with the same seriousness it applies to incriminating ones. Who received the overseas payment? Was that person an employee, contractor, or legitimate vendor? What did the invoice say? Why did the company use cash? What was normal for its industry, location, customers, and stage of growth? Did its owners seek legal and compliance advice? Did they report suspicious transactions when the law required it? Did the records show concealment, or did they show an imperfect company trying to build responsibly?
Without those questions, a system designed to identify risk can manufacture the appearance of guilt.
SECTION 03
Technology expanded the government's vision
American privacy law developed when records were scattered among paper files, bank branches, telephone companies, and physical offices. The government could obtain information from third parties, but practical limits restricted how much of a person's life could be assembled at once.
Those practical limits have largely disappeared.
Digital records can now be collected, searched, connected, and retained at a scale that earlier generations could not have imagined. Bank transactions can be compared with device data, communications, travel, account registrations, blockchain activity, and information supplied by private companies. Blockchain records add another dimension because transactions remain publicly traceable long after they occur.
The Supreme Court recognized part of this transformation in Carpenter v. United States. The case concerned historical cellphone location information, not financial records, but its reasoning matters. The Court refused to assume that old privacy rules automatically resolved the constitutional consequences of a new technology capable of revealing an extensive record of a person's movements.
Financial surveillance deserves the same serious examination.
The fact that a bank, exchange, payment company, or cryptocurrency business possesses information should not mean the government receives unlimited authority to reconstruct a person's life without meaningful safeguards. People cannot participate in modern society without entrusting information to intermediaries. That is not the same as consenting to unrestricted government examination.
The law should distinguish between targeted investigation and mass availability. It should consider how much data is collected, how long it is retained, who can search it, what suspicion is required, and whether anyone outside the investigating agency can review the decision.
Without those limits, surveillance expands because the technology permits it, not because justice requires it.
SECTION 04
The danger of beginning with a conclusion
Every investigation begins with a theory. The danger appears when the theory becomes a conclusion before all the evidence has been examined.
Once investigators become convinced that a company or individual is guilty, ordinary ambiguity can be interpreted in only one direction. A compliance error becomes concealment. An informal statement becomes an admission. A customer complaint becomes knowledge of a broader scheme. Evidence that supports the theory receives attention. Evidence that complicates it becomes background noise.
This is not a problem unique to financial investigations. It is a human problem intensified by government power.
Investigators control which records to collect, which witnesses to approach, which conversations to record, which excerpts to transcribe, and which facts to present to prosecutors. Prosecutors decide which charges to pursue and how to describe the evidence to a grand jury. By the time a defendant sees the government's theory, years of interpretation may already be embedded inside it.
That is why procedure matters. The presumption of innocence is not a ceremonial phrase reserved for the courtroom. It should influence how evidence is gathered, preserved, interpreted, and disclosed from the beginning.
An investigation committed to the truth asks, "What happened?"
An investigation committed to a conviction asks, "How can we make these facts prove our theory?"
Those questions can produce very different forms of justice.
SECTION 05
A theory can expose an entire private life
Once a theory takes hold, the government can seek increasingly intrusive information. Depending on the facts and the legal authority obtained, investigators may use subpoenas, search warrants, court-authorized wiretaps, location records, account histories, recorded conversations, and confidential informants. Used lawfully and narrowly, these tools can uncover serious crimes. Used without discipline, they can turn an unproven hypothesis into an examination of nearly every part of a person's life.
The distinction matters. A judge authorizing a search or wiretap does not establish that the target is guilty. It permits a defined investigative step based on a legal showing. The government must still remain within the authority it received, follow applicable necessity and minimization requirements, preserve evidence fairly, and prove every element of an offense beyond a reasonable doubt.
Financial records can expose a person's movements and relationships. Communications can reach further. Messages between spouses, relatives, friends, and business partners are rarely composed for an investigator, a prosecutor, or a jury. They contain shorthand, jokes, frustration, exaggeration, unfinished thoughts, and references that make sense only to the people involved. A sentence isolated from years of conversation may take on a meaning it never had when it was written.
The risk becomes greater when investigators begin with a criminal interpretation and read everything through it. A spouse asking about money can be portrayed as a participant. A friend offering advice can be treated as a conspirator. Concern about a customer, regulator, or bank can be described as consciousness of guilt. Ordinary privacy can be called secrecy. Once the theory controls the meaning, even an innocent denial may be characterized as another attempt to conceal the truth.
Confidential informants create another layer of risk. Informants can help expose genuine wrongdoing, but their words and conduct do not become reliable simply because the government recorded them. An informant may be paid, seeking leniency, facing charges, carrying a personal grievance, or following instructions intended to elicit particular statements. Those circumstances do not automatically make the evidence false. They make the informant's incentives, instructions, methods, and complete communications essential to evaluating it.
A broad investigation will almost always uncover something that can be made to look unusual. Every business has mistakes. Every long relationship contains arguments and awkward language. Every life produces contradictions when thousands of transactions and messages are examined years later. Volume can create the illusion of corroboration because investigators have more ambiguous details from which to select.
That is why suspicion cannot be allowed to validate itself. Before the government enters the private lives of innocent relatives, friends, employees, or customers, it should have lawful, particularized grounds for doing so. Once there, it should collect only what its authority permits, minimize irrelevant material, preserve full context, and disclose facts that undermine its theory. The greater the intrusion, the greater the obligation to be precise.
SECTION 06
Government misconduct is not justified by a worthy objective
Law enforcement sometimes needs to operate undercover. Investigators may use informants, controlled transactions, recorded conversations, and other deceptive techniques. Courts have long permitted many of these methods because certain crimes are difficult to uncover through ordinary observation.
Permission is not the same as a blank check.
The government should not manufacture criminal intent that did not previously exist. It should not pressure a person until exhaustion replaces judgment, cultivate impairment and later present the resulting speech as clear deliberation, or remove recorded statements from the circumstances that gave them meaning. It should not encourage conduct, omit its own role in producing that conduct, and then describe the result as spontaneous evidence of character.
Nor should prosecutors hide information that weakens the government's case. Under Brady v. Maryland and Giglio v. United States, the government has constitutional duties involving material exculpatory and impeachment evidence. The Department of Justice's own policy directs prosecutors to seek a just result and generally to err on the side of disclosure when materiality is close.
Those duties exist because the prosecution possesses advantages no defendant can reproduce. It commands investigators, subpoenas, databases, forensic resources, and the authority of the United States. A defendant cannot know what an agent omitted from a report or what a witness said in an interview that was never disclosed. When the government alone controls the missing information, fairness depends on the government honoring obligations that may work against its immediate desire to win.
Justice cannot mean using every lawful tool aggressively while treating constitutional duties as technical obstacles.
The prosecutor's role is not simply to obtain a conviction. It is to make sure that any conviction rests on evidence gathered and presented fairly.
SECTION 07
Compliance cannot become a promise of perfection
Financial regulation creates another risk when enforcement treats compliance as a guarantee that no customer will ever misuse a service.
No bank, money transmitter, cryptocurrency company, or payment platform can prevent every crime. A compliance program is a risk management system. It is designed to identify customers, detect warning signs, escalate concerns, maintain records, file reports, and improve as threats evolve. It is not proof against all human deception.
The government understands this when dealing with the largest banks. Major financial institutions have processed enormous volumes of unlawful transactions, opened unauthorized accounts, failed to monitor known risks, and violated consent orders. They have received fines, remediation plans, monitors, deferred prosecution agreements, and time to correct their systems.
Startups often receive a different kind of scrutiny. A young company may be judged as though it possessed the staff, software, data, and institutional experience of a global bank. A compliance officer may be criticized for lacking a prestigious résumé even when the company retained specialized attorneys, monitoring firms, consultants, and outside experts. Growth, remediation, and professional guidance can be dismissed as evidence that the earlier program was inadequate rather than proof that the company was trying to improve.
That approach confuses imperfection with bad faith.
The proper questions are concrete. Did the company establish a genuine program? Did it verify customers? Did it monitor activity? Did it file required reports? Did it respond to known problems? Did it seek qualified advice? Did it improve its systems? Most importantly, did the people accused of a crime possess the knowledge and intent required by the law?
Compliance evidence should be assessed honestly in both directions. Weaknesses should not be concealed. Efforts to comply should not be erased.
SECTION 08
Financial surveillance needs enforceable limits
The answer is not to eliminate financial intelligence. It is to govern it with rules strong enough to preserve legitimacy.
First, access should be tied to a defined investigative purpose. Agencies should not search broad financial databases merely because the information is available. Sensitive queries should require documented justification, and more revealing or prolonged surveillance should require stronger legal process.
Second, collection should be proportionate. Investigators should obtain the records relevant to the suspected conduct rather than entire financial histories whenever narrower production can answer the question.
Third, agencies should minimize and eventually delete information unrelated to the investigation. Innocent people should not remain permanently visible inside government systems because their transactions happened to intersect with someone under review.
Fourth, every search should leave an audit trail. Independent inspectors, courts, and appropriate oversight bodies should be able to determine who accessed financial intelligence, for what purpose, and how it was used.
Fifth, defendants must receive evidence necessary to challenge the government's account. That includes context surrounding recordings, information that contradicts an agent's interpretation, and evidence that casts doubt on the credibility or accuracy of prosecution witnesses.
Investigators should also document plausible innocent explanations and evidence that weakens their working theory. Red flags should be evaluated individually and in context. Their accumulation should never substitute for proof of the mental state required by law.
When private communications are collected, minimization must have practical force. Conversations unrelated to the investigation, particularly those involving spouses, children, relatives, and friends, should not become a permanent government archive or a source of prejudicial fragments. Complete recordings and surrounding messages should be preserved so that selected excerpts can be tested against their actual context.
When confidential informants are used, the defense and the court should receive the information the law requires about compensation, promised benefits, pending charges, instructions, credibility problems, and communications that contradict the government's presentation. A jury cannot fairly evaluate an informant without understanding why that person participated and how the evidence was produced.
Sixth, courts should apply meaningful remedies when rules are violated. A right without a remedy becomes advice. Evidence obtained through serious constitutional violations should face exclusion. Material disclosure failures should produce consequences capable of changing institutional behavior. Intentional misconduct should affect careers, not merely case files.
Finally, legislators should revisit privacy rules written for an earlier technological age. Financial intelligence has become too comprehensive to rely entirely on assumptions developed when data was fragmented and difficult to combine.
SECTION 09
Rights are tested when enforcement feels urgent
It is easy to defend civil liberties in cases involving sympathetic people and minor allegations. The real test comes when the accusation is frightening, the industry is unpopular, or the defendant is easy to portray as undeserving of concern.
Cryptocurrency makes that test harder. The industry has attracted fraud, reckless promotion, weak controls, and people who treated innovation as immunity from law. Those failures deserve a serious response. They do not justify lowering the standard of proof or abandoning constitutional limits for everyone who builds with the technology.
The government can investigate aggressively and still act honorably. It can follow money without assuming everyone who touched it shared the criminal purpose behind it. It can use undercover methods without manufacturing the meaning of the evidence. It can prosecute wrongdoing without hiding facts that favor the accused. It can protect the financial system without turning every participant into a permanent subject of suspicion.
That balance is not weakness. It is the discipline that separates lawful power from arbitrary power.
As a founder in financial technology, I do not ask for a world without oversight. I ask for oversight worthy of a free country. I want financial crime investigated, victims protected, and bad actors held accountable. I also want the government held to the standards it imposes on everyone else: accurate records, honest reporting, proportional action, documented decisions, and accountability when serious failures occur.
The state should never need to violate the principles of justice in order to prove that someone else violated the law.
When surveillance becomes unlimited, context becomes optional, and conviction becomes the objective at any cost, enforcement stops protecting the rule of law. It begins consuming it.
America does not preserve freedom by trusting that power will always be used wisely. It preserves freedom by placing limits on power, enforcing those limits when they are breached, and remembering that the rights of the accused belong to every person who may one day be accused.
That is where financial surveillance must stop.
