kill anyone or intend to kill anyone. By 1987, the counting of the states had shifted. In response to Enmund, four states had modified their capital punishment statutes to reject the death penalty for murder committed in the course of a felony when the participant exhibited reckless indifference to human life. Nevertheless, the Court observed in Tison that of the states that authorized the death penalty for felony murder, only 11 forbade it even for major participants in the felony who exhibited reckless indifference to human life. By the time of Tison, some state supreme courts had expressly interpreted Enmund to allow the death penalty in these cases. Sentencing decisions of juries "The jury... is a significant and reliable objective index of contemporary values because it is so directly involved" in the criminal justice system. In Enmund the Court recited that of 362 appellate decisions since 1954, only 6 involved a death sentence for a nontriggerman convicted of felony murder, and all 6 executions took place in 1955. This was comparatively rarer than death sentences for rape, of which there had been 72 between 1955 and 1977. Also, as of October 1, 1981, there were 796 people on death row in the United States, of whom only 3 had been sentenced to death absent a finding that the defendant had actually killed someone or intended that a killing take place. In Tison, however, the fact that since Enmund, state appellate courts continued to review and approve death sentences for defendants convicted of felony murder who were major participants in the underlying felony and had exhibited extreme indifference to human life persuaded the Court that juries still considered the death penalty an appropriate punishment for at least some defendants convicted of felony murder. Retribution and deterrence Faced with the objective evidence suggesting that legislatures and sentencing juries did not uniformly reject the death penalty for all defendants convicted of felony murder, the Court had to limit the death penalty to a discrete and narrow category of felony murder defendants based on its estimation of which category would best effectuate the goals of retribution and deterrence. The Enmund Court stressed that the propriety of the death penalty must be measured in light of Enmund's own conduct. The Tison Court added that historically, the individualized determination incorporates an assessment of the mental state with which the defendant commits a crime, because a more
