Violent crimes are offenses that involve the use, attempted use, or threatened use of physical force against another person. Federal law groups them under the label “crime of violence,” and the designation matters because it triggers harsher sentences, mandatory enhancements, and consequences that outlast the prison term itself. The category runs from a shove that qualifies as simple assault to premeditated murder, and the law treats each tier with a severity that non-violent offenses rarely carry.
How Federal Law Defines a Crime of Violence
The federal definition sits in 18 U.S.C. § 16. An offense qualifies if it has as an element the use, attempted use, or threatened use of physical force against another person or their property.1Office of the Law Revision Counsel. 18 USC 16 – Crime of Violence Defined Actual injury is not required. A credible threat of force can be enough.
The statute used to include a second, broader category covering any felony that “by its nature” carried a substantial risk that force might be used. The Supreme Court struck that provision down in 2018 in Sessions v. Dimaya, holding it unconstitutionally vague.2Supreme Court of the United States. Sessions v. Dimaya, 584 U.S. ___ (2018) Today the label turns on whether force is an actual element of the offense, not on a judge’s prediction about what might happen. The distinction drives outcomes in immigration cases, sentencing enhancements, and federal firearms charges, where “crime of violence” can add years or decades.
Homicide
Homicide is the top of the ladder, and federal law sorts it by the killer’s state of mind. First-degree murder requires premeditation and deliberate intent, or occurs during another dangerous felony like arson, kidnapping, robbery, or sexual abuse. The penalty is death or life in prison.3Office of the Law Revision Counsel. 18 USC 1111 – Murder Second-degree murder covers killings committed with malice but without premeditation and allows any term of years up to life.
Manslaughter sits a step below because malice is absent. Voluntary manslaughter, done in the heat of a sudden conflict, carries up to 15 years. Involuntary manslaughter, resulting from reckless or careless conduct rather than any intent to harm, carries up to 8 years.4Office of the Law Revision Counsel. 18 USC 1112 – Manslaughter The gap between a murder verdict and a manslaughter verdict can be the difference between dying in prison and walking out within a decade, which is why so much of a homicide trial focuses on what the defendant was thinking.
Assault
Assault spans a huge range of conduct, and 18 U.S.C. § 113 scales the penalties to match. Simple assault carries up to six months. Assault by striking or wounding carries up to a year.5Office of the Law Revision Counsel. 18 USC 113 – Assaults Within Maritime and Territorial Jurisdiction From there the ceiling climbs sharply:
- Assault with a dangerous weapon: up to 10 years
- Assault resulting in serious bodily injury: up to 10 years
- Assault with intent to commit murder: up to 20 years
Domestic conduct has its own tier. Strangling or suffocating a spouse, intimate partner, or dating partner carries up to 10 years. Assault causing substantial bodily injury to a spouse, partner, or child under 16 carries up to 5 years.
Robbery, Carjacking, and Arson
A theft crosses into violent-crime territory the moment force or intimidation enters the picture. Under the federal Hobbs Act, taking property from someone through actual or threatened force, violence, or fear of injury carries up to 20 years.6Office of the Law Revision Counsel. 18 USC 1951 – Interference With Commerce by Threats or Violence The same property taken when no one is present would carry far less.
Carjacking follows the same logic with sharper edges. Taking a motor vehicle from another person by force or intimidation carries up to 15 years. If the victim suffers serious bodily injury, the ceiling rises to 25 years. If someone dies during the carjacking, the sentence runs up to life or the death penalty.7Office of the Law Revision Counsel. 18 USC 2119 – Motor Vehicles
Federal arson escalates the same way. Destroying or damaging property by fire or explosives carries 5 to 20 years. If anyone is injured, the range becomes 7 to 40 years. If someone dies, the sentence can be 20 years to life, or death.8Office of the Law Revision Counsel. 18 USC 844 – Penalties
Sexual Violence
Sexual violence is classified as a violent crime because it involves physical violation without consent. Under federal law, aggravated sexual abuse through force or threats carries any term of years up to life. The same ceiling applies to rendering someone unconscious or drugging them to commit a sexual act.9Office of the Law Revision Counsel. 18 USC 2241 – Aggravated Sexual Abuse When the victim is under 12, or is between 12 and 16 and at least four years younger than the offender, the mandatory minimum is 30 years. A second federal conviction for sexual abuse of a child means life.
A conviction also triggers mandatory registration under the Sex Offender Registration and Notification Act. Registration follows a person across state lines and requires regular updates to law enforcement about where they live and work.10Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking. SORNA – Current Law Failing to register, or failing to keep registration current, is itself a federal crime carrying up to 10 years. If a person skips registration and then commits a violent federal crime, the registration violation alone carries up to 30 years.11U.S. Department of Justice. Citizens Guide to U.S. Federal Law on Sex Offender Registration
Domestic Violence and the Federal Firearm Ban
Domestic violence sits in its own category because even a misdemeanor conviction triggers a lifetime firearm ban. Under the Lautenberg Amendment, codified at 18 U.S.C. § 922(g)(9), anyone convicted of a misdemeanor involving the use or attempted use of physical force against a spouse, former spouse, co-parent, or someone they lived with is permanently prohibited from possessing a firearm or ammunition.12United States Department of Justice. Restrictions on the Possession of Firearms by Individuals Convicted of a Misdemeanor Crime of Domestic Violence
The ban reaches back to convictions that occurred before the law took effect in 1996. There is no exception for police officers or military personnel; a qualifying conviction prohibits carrying a firearm even on duty. The conviction must have involved counsel (or a knowing waiver), and if a jury trial was available, the defendant must have gone to trial or knowingly waived that right. Expungements and pardons generally lift the ban. A restoration of civil rights only works if it does not expressly allow firearm possession.
What Pushes a Sentence Higher
Certain facts transform a serious charge into something much worse.
Firearms
Under 18 U.S.C. § 924(c), using or carrying a firearm during a crime of violence adds a mandatory minimum of 5 years on top of the sentence for the underlying crime. Brandishing the firearm raises that minimum to 7 years. Discharging it raises the minimum to 10 years.13Office of the Law Revision Counsel. 18 USC 924 – Penalties These enhancements run consecutively, not concurrently, so they stack onto the base sentence instead of overlapping with it.
Victim Status
Crimes against children, elderly victims, and law enforcement officers carry heavier penalties under both federal and state law. Injuries that cause permanent disfigurement or significant impairment push sentences higher as well.
Hate Crime Enhancements
When violence is motivated by bias against race, religion, national origin, gender, sexual orientation, gender identity, or disability, federal hate crime law applies its own structure. Bias-motivated bodily injury carries up to 10 years. If the offense results in death, involves kidnapping or sexual abuse, or includes an attempt to kill, the ceiling becomes any term of years up to life.14Office of the Law Revision Counsel. 18 USC 249 – Hate Crime Acts A hate crime conspiracy resulting in death or serious bodily injury carries up to 30 years. Courts can also order educational classes or community service tied to the affected community as a condition of supervised release.
The Federal Three-Strikes Rule
Under 18 U.S.C. § 3559(c), a person convicted of a “serious violent felony” who has two or more prior serious violent felony convictions, or one such prior plus a serious drug offense, must be sentenced to life in prison.15Office of the Law Revision Counsel. 18 USC 3559 – Sentencing Classification of Offenses The statute names the qualifying offenses: murder, voluntary manslaughter, assault with intent to murder, robbery, carjacking, arson, kidnapping, aggravated sexual abuse, and certain firearms offenses, among others. Any other crime punishable by 10 or more years that involves force against another person also qualifies. Each prior conviction must have been final before the next offense was committed.
How Long Prosecutors Have to File Charges
For federal crimes punishable by death, including certain murders, there is no statute of limitations. Charges can be brought at any point.16Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses For non-capital federal violent crimes, the general deadline is five years from the date of the offense.17Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital
Some categories get longer windows. Non-capital terrorism offenses, including hostage-taking, attacks on diplomats, use of weapons of mass destruction, and aircraft piracy, carry an eight-year limitations period. Federal arson and explosives offenses carry a 10-year window.18U.S. Department of Justice. Criminal Resource Manual 650 – Length of Limitations Period State limitations periods vary, with most states imposing no deadline on murder and shorter windows for other violent offenses.
Defenses That Can Apply
A charge is not a conviction. Several recognized defenses can reduce or eliminate liability, though the defendant often carries the burden of proof.
Self-Defense
Both federal and state law recognize that a person may use reasonable force when they genuinely believe they face imminent death or serious bodily harm. The belief must be reasonable, measured from the perspective of a reasonable person in the defendant’s position at the time. The force used must also be proportional to the threat; a shove does not justify lethal force. Most states require that a safe retreat was not available before deadly force is used, though roughly half of states have “stand your ground” laws that remove the retreat requirement.
Insanity
Federal law allows insanity as an affirmative defense if, at the time of the offense, a severe mental disease or defect left the defendant unable to understand what they were doing or that it was wrong. The defendant must prove this by clear and convincing evidence.19Office of the Law Revision Counsel. 18 USC 17 – Insanity Defense A general mental illness or personality disorder is not enough. The statute also specifies that mental disease or defect “does not otherwise constitute a defense,” meaning this narrow path is the only one.
Duress
Duress applies when someone commits a violent act because they were threatened with imminent death or serious injury and had no reasonable chance to escape. Courts generally do not allow duress as a defense to murder, on the reasoning that no threat justifies taking an innocent life.
What a Conviction Costs Beyond Prison
The sentence is only part of the picture. Federal law permanently prohibits anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.20Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The ban is lifetime, with few exceptions, and violating it is a separate federal crime.
A felony conviction can disqualify you from jury service, bar you from certain professional licenses, and prevent you from holding public office. Non-citizens face a sharper problem: many violent offenses count as “aggravated felonies” under immigration law and can trigger mandatory deportation regardless of how long the person has lived in the country or what family ties they have. For anyone convicted of sexual violence, SORNA registration follows across state lines and can last for decades, affecting where the person is allowed to live and work.10Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking. SORNA – Current Law
Restitution is also mandatory, not optional. In cases involving crimes of violence with an identifiable victim who suffered physical injury or financial loss, the court must order the defendant to reimburse medical costs, therapy, rehabilitation, and lost income, along with expenses the victim incurred while participating in the investigation and prosecution, such as child care and transportation.21Office of the Law Revision Counsel. 18 USC 3663A – Mandatory Restitution to Victims of Certain Crimes The judge has no discretion to waive it. The prison term has an end date. Many of these other consequences do not.
