Federal Frequently Asked Questions & Legal Defense Guide
What is the difference between a federal crime and a state crime?
A federal crime is a violation of a statute enacted by the United States Congress, typically involving interstate activity, federal property, or national interests. A state crime is a violation of a law passed by a state legislature or local government entity that occurs within state boundaries.
Who investigates and prosecutes federal crimes?
Federal offenses are investigated by specialized federal law enforcement agencies, including the Federal Bureau of Investigation (FBI), Drug Enforcement Administration (DEA), Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), U.S. Secret Service, IRS Criminal Investigation (IRS-CI), and Homeland Security Investigations (HSI).
Cases are prosecuted by Assistant United States Attorneys (AUSAs) within the U.S. Department of Justice.
If I am charged with or under investigation for a federal offense, do I need a federal criminal defense lawyer?
Yes. To represent clients in federal court, an attorney must be admitted to practice before the specific U.S. District Court handling the case.
Furthermore, federal court involves distinct procedural rules, Federal Rules of Evidence, grand jury indictments, Pretrial Services, and complex U.S. Sentencing Guidelines that require specialized federal defense experience.
If I am under investigation for a federal offense but have not been charged, should I contact an attorney?
You should contact an experienced federal defense attorney immediately. Protecting your constitutional rights—such as your Fifth Amendment right against self-incrimination—during a pre-indictment investigation is critical.
Strategic legal intervention during the pre-charge stage can sometimes prevent charges from being filed altogether or mitigate potential exposure.
Can I be charged in both state and federal court for the same act?
Yes. Under the "Dual Sovereignty Doctrine," the federal government and state government are considered separate sovereign entities. As a result, both can legally prosecute you for the same conduct without violating double jeopardy protections, though federal policy generally limits dual prosecutions.
How do federal prison sentences differ from state prison sentences?
Federal crimes do not carry traditional parole. Under federal law, individuals convicted of federal offenses must serve at least 85% of their imposed prison term, even with earned credit for good behavior.
Additionally, federal sentences are heavily influenced by the mandatory and advisory U.S. Sentencing Guidelines.
What is a federal grand jury, and how does it work?
A federal grand jury consists of 16 to 23 citizens convened by a U.S. District Court to evaluate evidence presented exclusively by federal prosecutors. If the grand jury determines there is probable cause to believe a federal crime was committed, it issues a formal charging document known as an indictment.
What should I do if federal agents come to my house or workplace to question me?
You have the constitutional right to remain silent and the right to consult with an attorney. You should politely inform the agents that you are exercising these rights and will not answer questions without your lawyer present.
Attempting to explain yourself without counsel risks violating 18 U.S.C. § 1001 if any statement is deemed false or misleading.
What is a target letter from a federal prosecutor?
A target letter is a formal notification from a United States Attorney's Office informing an individual that a federal grand jury has gathered substantial evidence linking them to a federal crime.
Receiving a target letter means you are officially the primary subject of a criminal investigation and an indictment is imminent unless proactive defense measures are taken.
How does the federal bail and pretrial release process work?
Unlike state courts that frequently use standardized cash bail schedules, federal courts operate under the Bail Reform Act of 1984.
A Federal Magistrate Judge holds a detention hearing to determine whether a defendant presents a flight risk or a danger to the community. Release conditions are managed by Federal Pretrial Services and often involve signature bonds, property bonds, travel restrictions, or electronic monitoring rather than cash bail.
Are federal sentences governed by mandatory minimums?
Yes. Many federal statutes—particularly those involving drug trafficking (21 U.S.C. § 841), weapons offenses (18 U.S.C. § 924(c)), and child exploitation—carry strict statutory mandatory minimum prison sentences.
Federal judges cannot sentence below these statutory floors unless specific legal exceptions apply, such as the statutory "safety valve" (18 U.S.C. § 3553(f)) or substantial assistance motions filed by the government (Rule 35 / Section 5K1.1).
What is a federal proffer session and should I agree to one?
A proffer session (or "queen for a day" agreement) is a meeting where a subject or target, along with their defense attorney, provides information to federal prosecutors and agents. Under a written proffer agreement, the government agrees not to use statements made during the meeting directly against the individual in their main prosecution.
However, entering a proffer session carries significant legal risks and should only occur under the strict guidance of an experienced federal defense lawyer.
How long does a federal criminal investigation typically take before charges are filed?
Federal investigations often take months or even years before an arrest or indictment occurs.
Federal agencies conduct exhaustive pre-indictment work—including subpoenaing bank records, analyzing electronic devices, wiretapping communications, and executing search warrants—to build a comprehensive case before presenting evidence to a federal grand jury.
