Federal prosecutors say Luigi Mangione’s alleged crime didn’t end with the fatal shooting of UnitedHealthcare CEO Brian Thompson, it sparked a dangerous ripple effect that has already inspired more bloodshed. That, they argue, is why he should face the death penalty.In a new filing to the US Southern District of New York, prosecutors warned that Mangione is not just a murder suspect, but a symbol for others looking to turn grievances into violence, reported the Daily Beast.“Since the murder, certain quarters of the public, who openly identify as acolytes of the defendant, have increasingly begun to view violence as an acceptable, or even necessary, substitute for reasoned political disagreement,” wrote government attorney Sean Buckley.The filing points to last month’s deadly shooting inside NFL headquarters in New York City, where gunman Shane Tamura killed four people. Like Mangione, Tamura left behind writings to justify his attack and even etched the words “deny, defend, depose” onto his bullet casings, a chilling echo of Mangione’s alleged methods.Prosecutors say that proves Mangione’s killing of Thompson was calculated not just to target one man, but to “resonate beyond this specific victim” and to encourage scorn, outrage, and fear toward entire industries.“Simply put, the defendant hoped to normalize the use of violence to achieve ideological or political objectives,” the filing stated.Mangione’s lawyers have blasted the push for execution as a political stunt. “By seeking to murder Luigi Mangione, the Justice Department has moved from the dysfunctional to the barbaric,” they said, noting that local prosecutors had opposed the death penalty.Mangione is due back in court in December, though no trial date has been set.
