--------------------------------------------------------------------------------

Answer Key

  1. The three shell casings were inscribed with the words "Deny," "Delay," and "Depose." This is a modification of the phrase "Delay, Deny, Defend," a critique of insurance company tactics; replacing "Defend" with "Depose" transformed the message from a critique into a call for violent removal from power, serving as a form of manifesto.

  2. The "Privilege Paradox" refers to the question of how someone with every advantage, like Luigi Mangione, could choose to commit murder. He was a Gilman School valedictorian and University of Pennsylvania graduate from a family with an estimated fortune of over $37 million, yet he allegedly threw this future away for a planned assassination.

  3. Despite maintaining meticulous operational security by wearing a mask continuously for ten days, Mangione briefly lowered it to smile during a casual interaction with a hostel clerk. This unguarded moment was captured clearly by a security camera, providing the clean, unobscured image of his face that was essential for his public identification and eventual capture.

  4. A ghost gun is a privately made firearm, often assembled from 3D-printed frames and commercially available parts, that lacks a serial number. Its use posed a major challenge because it is untraceable, circumventing all federal firearms laws, background checks, and the entire chain of records that investigators typically use to follow a gun from manufacturer to buyer.

  5. Luigi Mangione faces prosecution in Pennsylvania for illegal firearm possession and forgery; in New York State for second-degree intentional murder and weapons charges; and in federal court for interstate stalking resulting in death and murder through use of a firearm, a charge that makes him eligible for the death penalty.

  6. The "Folk Hero Phenomenon" was the widespread and polarizing public support Mangione received after his arrest. Evidence includes social media campaigns like #FreeLuigi, commissary and legal defense donations exceeding $1.2 million, and polls showing significant portions of the public, especially younger demographics, viewed him sympathetically or favorably.

  7. The key forensic evidence was a discarded water bottle and KIND bar wrapper. These items proved invaluable because they contained the suspect's viable DNA from saliva and fingerprints, providing the biological certainty needed to link Luigi Mangione directly to the vicinity of the crime scene shortly before the murder occurred.

  8. Judge Carro dismissed the terrorism charges because the prosecution's evidence was "legally insufficient" to prove Mangione intended to intimidate or coerce a "civilian population" as required by the statute. The judge ruled that employees of a single company do not constitute a "civilian population" and that the act was a targeted, discrete killing, not an act designed to inspire widespread public fear.

  9. The defense argued that the federal death penalty charge was invalid because the underlying "crime of violence" prosecutors used was interstate stalking. They contended that stalking does not inherently involve the "use, attempted use, or threatened use of physical force" required by federal statute, and therefore cannot serve as the legal predicate for a capital murder charge.

  10. Luigi Mangione suffered from several chronic health issues, including Lyme disease, irritable bowel syndrome, and visual snow syndrome. His most significant challenge was spondylolisthesis, a spinal condition that caused severe, debilitating back pain, which was exacerbated by a surfing accident and was not fully resolved by spinal fusion surgery.

Essay Questions

The following questions are designed for longer, more analytical responses. Use evidence and examples from the source context to support your arguments. Answers are not provided.

  1. Analyze the concept of the "Privilege Paradox" in the case of Luigi Mangione. Using evidence from the text, discuss how his background of wealth and elite education contrasts with his alleged actions and how this paradox contributed to the public's fascination with the case.

  2. The text details a "tri-jurisdictional trap" facing the defendant. Describe the legal strategies and charges employed by Pennsylvania, New York State, and the federal government. Evaluate the constitutional challenges raised by the defense, such as the dual sovereignty doctrine and the application of the death penalty in a non-death-penalty state.

  3. Discuss the role of technology in this case, focusing on both the commission of the crime and the investigation. Analyze the significance of the 3D-printed ghost gun, the suspect's counter-surveillance awareness, and the use of digital surveillance (and fictional AI analysis) in building the case against him.

  4. Explore the theme of "America's Healthcare Rage" as a motivating factor in the crime and the subsequent public reaction. Using specific examples and statistics from the text, explain how widespread frustration with the health insurance industry fueled the "Folk Hero Phenomenon" and complicated the legal proceedings.

  5. The narrative highlights several critical mistakes or "vulnerabilities" in what was otherwise a meticulously planned operation. Identify and analyze at least two of these errors, explaining how they undermined the suspect's operational security and ultimately led to his capture.
