Summary

The dawn of the 21st century marked a turning point in the history of the American death penalty. Politically, the death penalty seemed vulnerable. A wave of abolitionism not seen since the Progressive Era took hold in the 2000s, as six states abandoned the death penalty, and governors in five others instituted moratoria, promising to use their executive power to stay all executions while they remained in office. While the Supreme Court remained committed to the constitutionality of the death penalty, it slowly chipped away at it in a series of decisions that narrowed the range of persons whom the state could execute.

Public support for the death penalty, already in decline during the late 1990s, continued to fall in the 21st century. A number of factors depressed support for the death penalty to levels not seen since the early 1970s: a decline in violent crime and fear of crime; highly publicized DNA-based exonerations of death-row inmates; and wariness of the cost of maintaining the death penalty, particularly during the great recession of the late 2000s.

The use of the death penalty was declining as well. The expansion of life without parole as an alternative punishment in the 1990s and 2000s gave juries in some states harsh alternatives to death sentences that they did not previously have. Longer-term changes to the judicial and penal administration of the death, meanwhile, continued to make the path between conviction and execution longer and more difficult for state officials to traverse. Most offenders sentenced to death since the 1970s were not (or have not yet been) put to death, and the average wait on death row for those who have been executed has grown to over a decade and a half. Growing problems with the practice of lethal injection, meanwhile, have posed new problems for states seeking to execute capital defendants in the 2000s, producing new legal battles and bringing executions nationwide to a temporary halt in 2007–2008.

The 2016 election of Donald J. Trump to the presidency of the United States, however, may portend a slowing or reversing Americans’ 21st-century turn away from the death penalty.
