Question 1

What exactly does 18 U.S.C. § 1519 cover, and how is it different from a straight obstruction charge under § 1503?

Accepted Answer

Section 1519 criminalizes destruction, alteration, or falsification of records in any federal investigation or bankruptcy proceeding—it doesn't require a pending court case. In my experience, prosecutors love this charge because it carries up to 20 years and applies broadly to documents, even emails or spreadsheets. The key difference from § 1503 is that § 1519 doesn't require an 'obstruction' of a specific judicial proceeding; it kicks in once a federal investigation is 'contemplated.'

Question 2

If I'm charged with a drug conspiracy under 21 U.S.C. § 846, can the government use statements from a co-defendant who pleads guilty but refuses to testify?

Accepted Answer

No—the Confrontation Clause under Bruton v. United States generally bars a non-testifying co-defendant's confession that incriminates you. But prosecutors often get around this by redacting names or using the statement in a separate trial. I've seen judges sever cases or allow limited use if the statement doesn't directly name you, so your defense needs to scrutinize every exhibit for Bruton violations.

Question 3

What's the 'willfulness' requirement under 26 U.S.C. § 7201 for federal criminal defense, and how do prosecutors prove it?

Accepted Answer

Willfulness means the defendant voluntarily and intentionally violated a known legal duty—not just negligence or a mistake. The government typically proves it through circumstantial evidence: lying to an accountant, destroying records, or using cash to avoid a paper trail. I've defended clients by showing they relied on professional advice in good faith, which negates willfulness even if the advice was wrong.

Question 4

How does the False Claims Act (31 U.S.C. § 3729) apply to healthcare providers, and what's the 'reverse false claim' theory?

Accepted Answer

The FCA imposes liability for knowingly submitting false claims for payment to the government. A 'reverse false claim' occurs when a provider knowingly conceals or improperly avoids an obligation to pay the government, like failing to refund overpayments. I've seen prosecutors use this aggressively in Medicare cases—they don't need an actual false invoice; just evidence you knew money was owed and didn't return it.

Question 5

What is the 'safety valve' under 18 U.S.C. § 3553(f), and can it help me avoid a mandatory minimum sentence in a drug case?

Accepted Answer

The safety valve allows a judge to sentence below a mandatory minimum if you meet five criteria: no more than one criminal history point, no violence or weapons, no leadership role, you cooperated fully, and the offense didn't involve death or serious injury. I've used this to get clients 5-year mandatory minimums reduced to 2–3 years. But beware—the government must agree your proffer was complete and truthful, so don't hold back.

Question 6

In a federal fraud case under 31 U.S.C. § 5324 (structuring), can the government charge me for making cash deposits under $10,000 to avoid reporting?

Accepted Answer

Yes—structuring is illegal even if each deposit is under $10,000 and the money is from a legal source. The statute prohibits splitting transactions to evade currency reporting requirements. I've seen prosecutors bring these charges even without proving the underlying source was illegal; they just need intent to avoid the bank's CTR filing. A strong defense often focuses on lack of knowledge of the reporting rules or that you had a legitimate business reason for the deposit pattern.

Question 7

What does 'specific intent' mean in a conspiracy charge under 18 U.S.C. § 371, and how do I fight it?

Accepted Answer

Specific intent for conspiracy requires proof you intended both to agree and to commit the underlying offense—not just to associate with others. The government often relies on ambiguous texts, phone records, or joint actions to infer intent. In my practice, I challenge this by showing the client had a lawful purpose (like a legitimate business deal) and that the alleged co-conspirators acted independently. If the government can't prove you knowingly joined the criminal objective, the conspiracy falls apart.

Question 8

If the FBI executes a search warrant at my home under 18 U.S.C. § 3109, do I have to let them in immediately, or can I demand to see the warrant first?

Accepted Answer

You can demand to see the warrant before permitting entry, but only if you do so immediately and without obstruction. Section 3109 requires agents to announce their purpose and authority before breaking in, but if you delay or refuse, they can lawfully force entry after a reasonable wait. I've advised clients to step back, say 'I want to see the warrant,' and comply—resisting or destroying evidence can add a separate obstruction charge under § 1519.

Question 9

How does the federal Sentencing Guidelines treat 'relevant conduct' under § 1B1.3 for drug quantity in a conspiracy?

Accepted Answer

Relevant conduct means you can be sentenced for all drug quantities reasonably foreseeable in the conspiracy, not just what you personally handled. For example, if your co-conspirator moved 50 kilos but you only touched 5, you could still face the 50-kilo guideline range. I've successfully argued that certain transactions were not foreseeable or that the government's quantity estimates relied on unreliable informants, which can drastically reduce the offense level.

Question 10

What is the 'public authority' defense under federal law, and when can I use it in a case involving ATF or DEA agents?

Accepted Answer

The public authority defense asserts that you reasonably relied on the official representation of a government agent that your conduct was legal. For example, if an ATF agent told you a firearm transfer was lawful, you may be able to argue you lacked criminal intent. However, this defense requires objective evidence—written authorization, recorded calls, or testimony from the agent—and is rarely successful without it. I've seen judges reject the defense if the agent lacked actual authority or if you knew the conduct was illegal despite the go-ahead.
