U.S. Capitol Police / Federal Law Enforcement Entrance (FLETC programs) U.S. Constitutional & Criminal Law for Federal Officers Syllabus

What are the two primary constitutional sources of federal criminal jurisdiction?

Congress's enumerated powers (especially the Commerce Clause and the Necessary and Proper Clause) and federal authority over federal property, persons, and interests.

What is 'special maritime and territorial jurisdiction' of the United States?

Federal jurisdiction over crimes committed on the high seas, U.S. vessels/aircraft, and federal enclaves such as military bases, national parks, and federal buildings (18 U.S.C. § 7).

What is the difference between federal and state criminal jurisdiction generally?

States have general police power to enact criminal laws, while the federal government may criminalize conduct only where it has a constitutional nexus (interstate commerce, federal property, federal officials/interests, etc.).

What does it mean for state and federal governments to have 'concurrent jurisdiction' over an offense?

Both sovereigns may prosecute the same conduct; under the dual sovereignty doctrine, successive prosecutions by state and federal governments do not violate double jeopardy.

What are the elements of the federal crime of assaulting a federal officer (18 U.S.C. § 111)?

Forcibly assaulting, resisting, opposing, impeding, intimidating, or interfering with a designated federal officer while that officer is engaged in or on account of official duties.

What are the general elements that the government must prove for any crime?

The actus reus (guilty act/voluntary conduct) and the mens rea (guilty mind/required mental state), occurring concurrently, plus causation and any specified result or attendant circumstances.

What are the elements of conspiracy under federal law (18 U.S.C. § 371)?

(1) An agreement between two or more persons to commit a federal offense or defraud the U.S., (2) knowing and voluntary participation, and (3) an overt act by at least one conspirator in furtherance of the agreement.

What distinguishes robbery from theft/larceny?

Robbery is the taking of property from a person or their presence by force or threat of force (violence); larceny/theft is taking without the element of force or intimidation.

What are the four common-law mens rea / Model Penal Code culpability levels?

Purposely (intent), knowingly, recklessly (conscious disregard of a substantial risk), and negligently (failure to perceive a substantial risk).

What is the difference between 'specific intent' and 'general intent' crimes?

Specific intent requires intent to bring about a particular additional result (e.g., burglary = breaking and entering with intent to commit a felony); general intent requires only intent to perform the prohibited act.

What is a strict liability offense?

A crime requiring no proof of mens rea — guilt attaches from the act alone (e.g., certain regulatory or public-welfare offenses).

What is transferred intent?

When a defendant intends to harm one person but instead harms another, the intent 'transfers' so the defendant is liable as though the intended victim were harmed.

What is the difference between 'actus reus' and 'mens rea'?

Actus reus is the physical, voluntary criminal act (or omission where a duty exists); mens rea is the defendant's culpable mental state at the time of the act.

List the major recognized exceptions to the search warrant requirement.

Consent, search incident to lawful arrest, automobile (vehicle) exception, plain view, exigent circumstances, stop and frisk (Terry), hot pursuit, and inventory searches.

What is the scope of a search incident to a lawful arrest?

Officers may search the arrestee's person and the area within their immediate control ('wingspan') to find weapons and prevent destruction of evidence (Chimel v. California).

What is the automobile exception to the warrant requirement?

Officers with probable cause to believe a vehicle contains contraband or evidence may search it without a warrant, due to its mobility and reduced expectation of privacy (Carroll v. United States).

What is the plain view doctrine?

Officers may seize evidence without a warrant if they are lawfully present, the item's incriminating nature is immediately apparent, and they have lawful access to the object.

What are exigent circumstances justifying a warrantless entry?

Emergencies such as imminent destruction of evidence, hot pursuit of a fleeing suspect, risk of escape, or danger to life that make obtaining a warrant impractical.

What must valid consent to a search be?

Voluntary (not coerced) and given by a person with actual or apparent authority over the area; the scope is limited to what a reasonable person would understand the consent to cover.

What is an inventory search and why is it allowed?

A routine, warrantless cataloging of property in lawfully impounded vehicles or arrestees' effects, allowed for administrative purposes (protect property, protect police from claims/danger), not investigation.

What is the difference between an investigative detention (Terry stop) and an arrest?

A Terry stop is a brief, limited detention based on reasonable suspicion; an arrest is a full custodial seizure requiring probable cause.

What level of suspicion is required for a Terry stop, and what may officers do?

Reasonable, articulable suspicion that criminal activity is afoot; officers may briefly detain and, if they suspect the person is armed and dangerous, conduct a limited pat-down (frisk) for weapons (Terry v. Ohio).

What is the difference between 'reasonable suspicion' and 'probable cause'?

Reasonable suspicion is a lower standard — specific, articulable facts suggesting criminal activity (justifies a stop); probable cause is a higher standard — facts warranting a reasonable belief a crime occurred (justifies arrest/search).

What factors indicate a detention has escalated into an arrest requiring probable cause?

Length and intrusiveness of the detention, use of restraints/handcuffs, transport of the suspect, show of force/weapons, and whether a reasonable person would feel free to leave.

What is required for a valid federal arrest warrant?

It must be issued by a neutral magistrate upon a sworn complaint establishing probable cause, and it must name or describe the person to be arrested (Fed. R. Crim. P. 4).

When may a federal officer make a warrantless arrest?

For a felony when the officer has probable cause to believe the person committed it, and for offenses (including misdemeanors) committed in the officer's presence, as authorized by statute.

What is a 'prompt presentment' or Gerstein requirement after a warrantless arrest?

An arrestee must be brought before a magistrate without unnecessary delay (generally within 48 hours) for a judicial determination of probable cause (Gerstein v. Pugh; County of Riverside v. McLaughlin).

What conduct does 42 U.S.C. § 1983 address?

It creates a civil cause of action against state/local officials who, acting under color of state law, deprive a person of federal constitutional or statutory rights.

What is the criminal civil-rights statute 18 U.S.C. § 242?

It criminalizes the willful deprivation, under color of law, of any rights, privileges, or immunities secured by the Constitution or U.S. laws (e.g., excessive force by an officer).

What is qualified immunity and what is its two-part test?

A doctrine shielding government officials from civil liability unless (1) they violated a constitutional/statutory right and (2) that right was 'clearly established' at the time, such that a reasonable official would have known the conduct was unlawful.

What are key liability risk-management practices for federal officers?

Acting within policy and the scope of authority, using only objectively reasonable force, thorough and accurate documentation/reports, ongoing training, de-escalation, and adherence to constitutional standards for stops, searches, and arrests.
