Federal criminal prosecution differs fundamentally from state prosecution. Federal crimes are investigated by agencies with vast resources, prosecuted by experienced assistant U.S. attorneys, and tried in courts with different rules and cultures. The stakes are typically higher, the sentences longer, and the process more complex than state court.
Federal Jurisdiction
Constitutional authority limits federal criminal law. Federal crimes must rest on enumerated powers including interstate commerce, taxation, and regulation of federal lands.
Interstate commerce provides the most common jurisdictional hook. Any activity substantially affecting interstate commerce can be federally criminalized.
Federal property and facilities create jurisdiction. Crimes on military bases, in federal buildings, and on other federal property are federal offenses.
Crimes against federal officers and obstruction of federal functions are inherently federal.
Dual sovereignty allows both federal and state prosecution for the same conduct. Double jeopardy does not bar successive prosecutions by different sovereigns.
Common Federal Offenses
Drug trafficking under 21 U.S.C. § 841 is among the most prosecuted federal crimes. Mandatory minimums create severe sentencing exposure.
Fraud crimes including wire fraud, mail fraud, bank fraud, and healthcare fraud carry significant penalties. Federal fraud statutes are interpreted broadly.
Firearms offenses under 18 U.S.C. § 922 and § 924 include felon in possession, straw purchases, and use of firearms in drug trafficking.
Immigration crimes including illegal entry, illegal reentry, and document fraud are heavily prosecuted in border districts.
White collar crimes including tax evasion, money laundering, and securities fraud are federal priorities.
RICO provides enhanced penalties for patterns of racketeering activity. Enterprise liability reaches organized criminal activity.
Child exploitation offenses are prosecuted federally due to internet jurisdiction and sentencing disparity.
Federal Investigation
Federal agencies including FBI, DEA, ATF, IRS, and HSI conduct investigations. Agency resources exceed most state counterparts.
Grand jury investigation compels testimony and document production. Subjects may not know they are targets until indictment.
Proactive investigation techniques include wiretaps, undercover operations, and cooperating witnesses. Federal resources enable sophisticated investigation.
Target letters notify subjects of investigation. Receipt of a target letter requires immediate legal response.
Pre-indictment negotiation may resolve cases before charges. Early intervention can influence charging decisions.
Federal Court Procedures
Indictment by grand jury is constitutionally required for felonies. Grand juries hear only prosecution evidence and almost always indict.
Initial appearance and detention hearing determine whether defendants await trial in custody. Detention is common in federal court.
Discovery in federal court is governed by Rule 16 and the Jencks Act. Disclosure obligations are more limited than in many state courts.
Plea agreements resolve most federal cases. Guidelines calculations and cooperation agreements shape negotiations.
Sentencing follows federal sentencing guidelines. Judges calculate advisory ranges and may vary based on 18 U.S.C. § 3553 factors.
Federal Sentencing
Sentencing guidelines provide advisory ranges based on offense characteristics and criminal history. Base offense levels are adjusted for specific conduct.
Mandatory minimums remove judicial discretion for certain offenses. Drug quantities, firearms involvement, and prior convictions trigger minimums.
Substantial assistance departures reward cooperation. Providing information leading to prosecution of others can reduce sentences below mandatory minimums.
Safety valve allows first-time, non-violent drug offenders to avoid mandatory minimums by providing complete information.
Post-Booker sentencing gives judges discretion to vary from guidelines. Reasonableness review applies on appeal.
Federal Appeals
Direct appeal to circuit courts reviews legal errors. Preserved issues receive de novo review. Unpreserved issues require plain error.
Habeas corpus under 28 U.S.C. § 2255 challenges convictions based on constitutional violations. Ineffective assistance of counsel is common ground.
Sentence reduction under 18 U.S.C. § 3582 is available when sentencing guidelines are retroactively reduced.
Compassionate release under 18 U.S.C. § 3582(c)(1)(A) allows early release for extraordinary circumstances.
Federal Defender Services
Federal public defenders provide representation to indigent defendants. CJA panel attorneys supplement when conflicts or resources require.
Quality of federal defense representation is generally high. Federal defenders are experienced and well-resourced compared to many state public defenders.
Private counsel brings additional resources and focus. Complex cases benefit from dedicated representation.
For Service Members
Federal prosecution affects service members differently than civilian defendants.
Dual jurisdiction between federal courts and courts-martial means the same conduct can be prosecuted in either or both forums. Coordination between DOJ and military justice is common.
Off-base federal crimes may be prosecuted in federal court rather than by court-martial. Where prosecution occurs affects procedures and sentencing.
Federal conviction consequences include UCMJ action regardless of where prosecution occurs. Federal convictions trigger administrative separation in most cases.
Leavenworth and other federal military prisons house military and civilian federal prisoners. Prison designation depends on multiple factors.
Security clearance is lost upon federal conviction. Investigation-stage involvement also affects clearances.
Cooperation with federal prosecutors creates complex considerations for service members. Immunity, debriefing, and testimony obligations require careful navigation.
SCRA protections may delay federal proceedings. Service members unable to participate due to military duties can seek continuances.
Federal public defenders and CJA panel attorneys represent military defendants in federal court. Coordination with military counsel may be necessary.
A military attorney understands the intersection of federal prosecution with military justice, how federal convictions affect military careers, and how to coordinate defense across jurisdictions.
