What Is a Federal Sex Crime?
Sex crimes usually refer to non-consensual conduct or acts that are legally prohibited even when consent exists, such as prostitution, sex trafficking, or public indecency. Ordinarily, state authorities handle these types of charges.
Federal sex crimes cover many of the same offenses; however, you’ll have the full strength of the United States government against you instead of just the state.
Federal sex crimes bring extraordinary penalties and long-term repercussions. People convicted of these offenses often face:
- Lengthy prison terms that may span decades
- Federal mandatory minimum sentences in specific trafficking and exploitation matters
- Lengthy post-prison supervision requirements
- Requirements to register as a sex offender
- Restrictions on where they can live and work
- Irreversible damage to reputation, employment prospects, and family life
When Does a Sex Crime Become Federal?
Most sex crimes are generally charged at the state level. Federal jurisdiction takes over when the offense involves federal land, crosses state lines, or makes use of nationwide systems like the internet or postal services.
Federal prosecutors in San Francisco, CAvvvvv often take over sex crime cases when one of the following applies:
- Crossing state lines while attempting or committing sexual offenses
- Using the internet, social media, or apps to facilitate or attempt prohibited sexual conduct
- Using the mail or other interstate services to send prohibited materials or messages related to a sexual crime
- Offenses on federal property, like federal buildings, correctional facilities, parks, or military bases
- Crimes that involve federal interests, including offenses involving federal workers or federal government programs
Who Investigates Federal Sex Crimes?
Federal sex crime investigations are often handled by agencies with specialized units and large resources. These agencies may include:
- The Federal Bureau of Investigation (FBI)
- Homeland Security Investigations (HSI)
- United States Postal Inspection Service
- Federal military police and other investigative branches
If you are contacted by one of these agencies about a sex offense, the situation is immediately high-risk. Do not participate in questioning, make statements, or approve searches until speaking with a seasoned San Francisco, CA federal sex crime defense attorney.

Types of Federal Sex Crimes We Defend in San Francisco, CA
There are dozens of federal sex crimes found in Title 18 of the U.S. Code. While our San Francisco, CA federal sex crime lawyers are prepared to defend you against any of them, these are the most common charges we see:
Sexual Abuse and Aggravated Sexual Abuse
Under federal law, sexual abuse and aggravated sexual abuse include cases involving force, threats, or victims who cannot legally consent
- Sexual assault that uses violence or threats of violence
- Offenses against individuals who cannot legally or physically consent due to impairment
- Sexual misconduct involving minors or vulnerable adults on federal property
Child Sexual Exploitation and Child Pornography
Federal child exploitation statutes are aggressively enforced nationwide. Common federal allegations include:
- Sexual exploitation of children, sometimes known as child pornography production
- Distribution and receipt of child pornography, including online or electronic distribution methods
- Possession of child pornography, including images or videos on computers, phones, or cloud storage
- Exploiting a minor to generate explicit images or real-time video
Production offenses almost always carry mandatory minimum prison sentences. Possession may still bring long terms of imprisonment, lifetime release conditions, and required sex offender registration.

- Coercion and enticement of a minor through internet-based communication or messaging apps
- Traveling with intent to engage in illegal conduct with someone believed to be a minor

- Using force, threats, or coercion to make someone engage in sexual activity in exchange for money, shelter, drugs, or anything of value

- Moving a person across state boundaries for unlawful sexual conduct
- Forcing or deceiving a person into being transported for sexual exploitation
