Justifications and Excuses in Criminal Law: Case Analyses
This paper examines four distinct criminal law scenarios to explore the doctrines of justification and excuse as defenses to criminal liability. The cases involve a man coerced into robbing a bank under threat to his wife's life, a man charged with bigamy after reasonably believing his divorce was finalized, parents held accountable when their child accidentally shoots a playmate with an unsecured firearm, and two drivers arrested near a bar for suspected drunk driving. Drawing on the Model Penal Code and relevant case precedents, the paper evaluates which legal defenses apply, what evidence would be required, and how mitigating circumstances such as age and reasonable belief affect criminal responsibility.
- Duress and Bank Robbery: Adam's Case: Coerced robbery, duress defense, corroborating evidence
- Bigamy and Honest Mistake: Charles's Case: Good-faith belief, Model Penal Code bigamy defense
- Parental Liability and Firearm Access: Bob and Brandy's Case: Parents liable for child's access to unsecured firearm
- DUI Arrests and the Viability of Defense: Breathalyzer evidence limits DUI defense options

What makes this paper effective
- Each scenario is analyzed discretely and methodically, keeping the legal reasoning focused and easy to follow.
- The paper grounds abstract legal concepts in real-world precedents and case examples, giving the analysis credibility and practical relevance.
- The discussion of mitigating factors — such as a child's age or a defendant's honest belief — demonstrates an understanding of nuance in criminal liability.
Key academic technique demonstrated
The paper applies the issue-rule-analysis-conclusion (IRAC) pattern informally across each scenario: it identifies the legal issue, invokes the applicable rule or standard (such as the Model Penal Code's good-faith defense for bigamy), applies that rule to the facts, and reaches a reasoned conclusion. This structured approach is a core skill in legal and criminal justice writing at the undergraduate level.
Structure breakdown
The paper is organized into four self-contained case studies, each presenting a fact pattern followed by a legal analysis. The conclusion of each section flows naturally from the facts and doctrine introduced. The works cited section uses APA-style formatting. The overall structure mirrors a problem-based examination common in criminal justice and pre-law undergraduate coursework.
Duress and Bank Robbery: Adam's Case
As Adam leaves the bank and approaches his car, he sees his wife behind the wheel with an unknown man seated next to her, holding an object to her side. Another man approaches Adam and informs him that he and his partner will kill Adam's wife unless Adam robs the bank and returns to the parking lot within five minutes. The man hands Adam a stick-up note and a fake gun. Adam robs the bank and delivers the money to the men. Adam is subsequently arrested for bank robbery.
There have been cases in the past where innocent individuals were forced to rob banks — threatened at gunpoint, with family members held hostage, or even fitted with explosives and told a bomb would detonate if they refused. In 2012, a woman was forced to rob a bank while a gunman held her children hostage at home (Velasquez, 2012). Under such circumstances, a defendant must prove that he was not a willing participant but was, in fact, a victim. The defense of duress requires corroborating evidence to be credible.
To establish this defense, Adam would need to produce the fake gun or demonstrate that the stick-up note was not written in his handwriting. His wife's testimony would be valuable, but additional corroboration would strengthen the case considerably. For example, if the bank teller with whom Adam interacted noticed that he appeared visibly upset or fearful — rather than forward and confident — that observation could support his account. The totality of such evidence would be essential for a successful duress defense.
Bigamy and Honest Mistake: Charles's Case
After a whirlwind romance, Charles marries Caroline. The relationship sours and Caroline leaves. Some months later, Charles receives a divorce petition along with a letter from Caroline's lawyer stating that unless he contests, the divorce will be granted in 90 days. Charles remarries two years later, this time to Delia. Delia, convinced that Charles is being unfaithful, hires a private detective to investigate him. The detective discovers that Charles's divorce from Caroline was never finalized because Caroline failed to pay the required court fees. Delia reports the matter to her brother, a police officer, and Charles is arrested for bigamy.
According to the Model Penal Code, as long as Charles legitimately and honestly believed his first marriage was legally dissolved, he may use that belief as a defense against bigamy charges (Loewy, 1975, p. 131). Because he genuinely understood that he and Caroline were divorced, he cannot be successfully prosecuted for bigamy on those facts alone. If, however, the prosecution can demonstrate that Charles knew his divorce was not final — that he was aware Caroline had not paid the required fees — then bigamy charges could be sustained.
Parental Liability and Firearm Access: Bob and Brandy's Case
Bob and Brandy own a pistol registered in Bob's name. They keep it in the drawer of their bedroom nightstand. One day, their eight-year-old son, Tom, is playing in the room with his friend Sandy. Tom finds the pistol and accidentally shoots Sandy.
In situations like this, parents are typically held accountable for their children's access to unsecured firearms. In 2013, for instance, a man was charged with endangering the welfare of a child and disorderly conduct after his four-year-old fatally shot a six-year-old with the family's gun (Jones, 2013). Firearm safety guidelines consistently advise gun owners to store weapons securely and unloaded, particularly in households with children. In this case, the pistol was kept in an easily accessible location and was apparently loaded — both of which represent serious lapses in responsible gun ownership on the part of the parents.
As for Tom's age, children under seven are generally not held criminally accountable because they are presumed incapable of understanding the severity of their actions. At eight years old, Tom occupies a more ambiguous legal position. He would likely be ordered to attend counseling to address the psychological impact of the incident and to prevent future accidents. However, with respect to criminal charges, the parents are far more likely to face legal consequences than Tom himself. His age would serve as a significant mitigating circumstance, substantially reducing, if not eliminating, his criminal exposure.
