CCJS 230: Criminal Law in Action

A guide to UMGC's CCJS 230, the course on how criminal cases are charged, the elements of crimes and the defenses that negate liability.

Updated October 2026 · 5 min read

CCJS 230 Criminal Law in Action is a University of Maryland Global Campus course on how criminal cases are charged and what makes someone criminally liable.

UMGC describes it as an exploration of how criminal cases are handled, including factors in how a case is charged and criminal liability. The focus is on the substantive elements of criminal law and its historical development in the United States.

Topics include the basic elements of and defenses to criminal liability, crimes against people, crimes against property, and the defenses and justifications used to negate criminal responsibility. CCJS 100 is the prerequisite.

Students find the precision demanding. A fact pattern must be broken into elements, and each element must be proven by specific facts.

Key Concepts Explained

Actus Reus and Mens Rea

Most crimes need a guilty act (actus reus) and a guilty mind (mens rea) occurring together. The Model Penal Code grades mental states from most to least culpable: purposely, knowingly, recklessly and negligently.

Justifications Versus Excuses

A justification says the act was right in the circumstances, such as self-defense. An excuse says the act was wrong but the person is not blameworthy, such as insanity or duress. The distinction matters in exam answers.

Using IRAC

IRAC (Issue, Rule, Application, Conclusion) is a reliable structure for fact patterns.

Example: Sam enters an unlocked garage at night intending to take a bicycle, and leaves with it. Issue: is this burglary, larceny or both? Rule: burglary statutes typically require unlawful entry into a structure with intent to commit a crime inside; larceny is taking another's property with intent to permanently deprive. Application: Sam entered without permission with intent to steal (burglary elements met, depending on whether the state treats a garage as a covered structure) and took the bicycle intending to keep it (larceny). Conclusion: Sam can likely be charged with both, subject to the state's statutory definitions.

Defenses in Practice

Defenses often turn on specific elements. Self-defense usually requires a reasonable belief in imminent unlawful force and a proportionate response; deadly force needs a threat of death or serious injury, and some states impose a duty to retreat while others have stand-your-ground laws.

Insanity tests vary by jurisdiction. The M'Naghten rule asks whether the defendant knew the nature of the act or that it was wrong; other states use the Model Penal Code's substantial capacity test. Always check which rule the scenario's jurisdiction uses.

How Offenses Are Graded

The same harm can be charged at different levels depending on mental state and circumstances. Homicide shows this clearly.

OffenseTypical mental state
First-degree murderPremeditated, deliberate intent to kill
Second-degree murderIntent to kill without premeditation, or extreme recklessness
Voluntary manslaughterIntentional killing in the heat of passion after adequate provocation
Involuntary manslaughterDeath caused by recklessness or criminal negligence

Exact definitions vary by state, so cite the statute used in your course materials.
