Use Cases

When People Seek This Expertise

Grand Jury Subpoenas & Target Letters

The first document from a federal investigation sets the tone for everything after it. Former prosecutors know what a subpoena's scope signals about the government's theory, how subject, target, and witness designations differ, and which early moves narrow exposure rather than widen it.

Internal Investigations

A whistleblower complaint or audit finding demands an inquiry that will stand up to later government scrutiny. People who assessed corporate investigations at the DOJ or SEC know what regulators treat as credible — scoping, privilege, documentation, and remediation.

The Self-Disclosure Decision

DOJ's Department-wide corporate enforcement policy rewards voluntary disclosure with declinations, but the judgment of whether, when, and to whom is unforgiving. Former officials who administered these incentives understand how disclosure timing and cooperation credit are actually weighed.

Foreign Bribery & Anti-Corruption Exposure

Anti-corruption enforcement has been recalibrated to prioritize cases touching US interests, but the statute hasn't changed. Former Fraud Section prosecutors bring first-hand judgment on the FCPA's jurisdictional reach, third-party risk, and what a defensible anti-bribery program looks like.

False Claims Act & Trade Fraud

Qui tam relators drive government-program fraud cases under the False Claims Act, and customs duty evasion is now a stated priority with nine-figure resolutions behind it. Former civil-division and enforcement lawyers know how these cases are built, valued, and settled.

Compliance Programs & Monitorships

Prosecutors assess compliance against the DOJ's Evaluation of Corporate Compliance Programs when deciding charges and monitor requirements. Former insiders can benchmark a program the way the government would — before the government does.

Backgrounds

Where This Expertise Comes From

DOJ Criminal Division

The Fraud Section and Money Laundering and Asset Recovery Section run the government's flagship corporate crime cases. Former trial attorneys and supervisors map to foreign bribery matters, self-disclosure strategy, and monitorship negotiation.

US Attorneys' Offices

Former Assistant US Attorneys prosecuted fraud, laundering, and public corruption district by district. They map to grand jury practice, charging judgment, and the local knowledge that shapes how a case is actually handled.

FBI Financial Crime

Special agents build white collar cases — interviews, records, cooperating witnesses. Former agents map to internal investigations, evidence handling, and anticipating the government's next investigative step.

SEC Division of Enforcement

Investigates securities fraud, insider trading, and disclosure violations, often in parallel with criminal authorities. Former enforcement staff map to Wells process strategy and managing civil and criminal exposure at once.

IRS Criminal Investigation

The financial investigators behind tax and money-laundering prosecutions. Former special agents map to tracing funds and assessing criminal tax exposure.

FinCEN & OFAC

Administer the Bank Secrecy Act and sanctions regimes respectively. Former officials map to anti-money-laundering compliance, sanctions and export-control exposure, and reporting obligations.

HHS-OIG & State Attorneys General

Health-program fraud enforcement and state-level corporate investigations. Former staff map to healthcare fraud matters and coordinating multi-state exposure.

Why It Matters

Judgment You Can't Read in a Manual

Enforcement policy tells you what the government says it will do; people who exercised that discretion know how the decisions actually get made. Browse the ranked professionals above and contact the background that matches your situation directly.

FAQs

Working With These Professionals

Why engage a former prosecutor when I already have counsel?

Defense counsel argue your case; a former prosecutor tells you how the government will see it — what the office rewards, what irritates it, and where your real exposure lies. Most engagements complement an existing legal team rather than replace it.

Can I engage someone before there's any investigation?

Yes — much of the value is preventative: benchmarking a compliance program, pressure-testing an internal inquiry, or gaming out a disclosure decision before anything is on the government's radar.

Why does agency background matter when choosing someone?

Each agency runs its own playbook. Someone who has worked the SEC's Wells process, an FBI case build, or a DOJ charging decision brings judgment specific to the body you're dealing with — match the background to your matter.

Can these professionals serve as expert witnesses?

Many do — former enforcement officials testify on investigative standards, compliance adequacy, and industry practice, with credibility earned inside the agencies whose conduct is in question.

Is this only for large companies?

No — individuals facing personal exposure, small businesses, and counsel seeking a second opinion all engage through the directory. Scope and terms are agreed directly with the person you contact.

How do I engage someone listed here?

Profiles link directly to each member's contact details — no intermediary, no fee. Choose the person whose enforcement background matches your matter.
