This excerpt details the legal aftermath of the Tison gang crimes, focusing on the defense attorney's efforts to save the surviving brothers from the death penalty by appealing to the Supreme Court. It discusses the application of felony murder laws and analyzes the relevance of the precedent set by *Enmund v. Florida* (1982) regarding culpability and capital punishment. The text also highlights the challenges posed by the changing composition of the Supreme Court, specifically the appointments of conservative justices like Antonin Scalia and William Rehnquist.

HOUSE_OVERSIGHT_017252.jpg

This document is a page from a book manuscript (Chapter 12), likely written by Alan Dershowitz, discussing the legal defense of Ricky and Raymond Tison. It details the 'felony-murder' rule and the author's decision to represent the brothers pro bono in their appeal against the death penalty in Arizona. The text outlines the background of the case, where the brothers helped their father escape prison but did not personally kill anyone during the subsequent murders.
