NEW YORK (AP) — Six weeks before UnitedHealthcare CEO Brian Thompson was gunned down outside a Manhattan hotel in December, suspect Luigi Mangione mused about rebelling against “the deadly, greed fueled health insurance cartel” and said killing the executive “conveys a greedy bastard that had it coming,” prosecutors revealed Wednesday.

Prosecutors say, to Mangione, Thompson and UnitedHealthcare were symbols of the healthcare industry and what the 27-year-old considered a deadly greed-fueled cartel.

Luigi Mangione's defense argues that courtroom restraints, like handcuffs and a bulletproof vest, are unnecessary in the trial for the UnitedHealthcare assassination.

Luigi Mangione revealed he wanted to kill Thompson to "prove a political point about the health insurance industry."

Prosecutors have shared information from the notebooks of Luigi Mangione, the man accused of assassinating UnitedHealthcare CEO Brian Thompson last year. Joining “Banfield” to help unpack the information is Erik Uebelacker of Courthouse News Service.

Luigi Mangione made several diary entries that reveal his thoughts prior to the December shooting of UnitedHealthcare CEO Brian Thompson, of which he is accused, New York City prosecutors claim in a new court filing.

Luigi Mangione wrote of an “unjustified catastrophe” he considered before deciding to attack an insurance executive, court records show.

His defense lawyer, Karen Agnifilo Friedman, requested that the top charge be dropped because, she said, it should not be applied to the death of a single person. The Manhattan District Attorney filed an 82-page brief opposing Luigi Mangione's effort to drop his terrorism charges.
