n Canada, Australia, New Zealand, Latin America, and Western Europe, the death penalty has become relatively unpopular, with the majority of the population opposing it. However certain cases of mass murder, terrorism, and child murder occasionally cause waves of support for reinstitution, such as the Greyhound bus beheading, Port Arthur massacre and Bali bombings. Between 2000 and 2010, support for the return of capital punishment in Canada dropped from 44% to 40%, and opposition to it returning rose from 43% to 46%.
Abolition was often adopted due to political change, as when countries shifted from authoritarianism to democracy, or when it became an entry condition for the European Union. The United States is a notable exception: some states have had bans on capital punishment for decades (the earliest is Michigan, where it was abolished in 1847), while others actively use it today. The death penalty there remains a contentious issue which is hotly debated. Elsewhere, however, it is rare for the death penalty to be abolished as a result of an active public discussion of its merits.[citation needed]
In abolitionist countries, debate is sometimes revived by particularly brutal murders, though few countries have brought it back after abolishing it. However, a spike in serious, violent crimes, such as murders or terrorist attacks, has prompted some countries (such as Sri Lanka and Jamaica) to effectively end the moratorium on the death penalty. In retentionist countries, the debate is sometimes revived when a miscarriage of justice has occurred, though this tends to cause legislative efforts to improve the judicial process rather than to abolish the death penalty.

A Gallup International poll from 2000 said that “Worldwide support was expressed in favor of the death penalty, with just more than half (52%) indicating that they were in favor of this form of punishment.” A number of other polls and studies have been done in recent years with various results.
In a poll completed by Gallup in October 2009, 65% of Americans supported the death penalty for persons convicted of murder, while 31% were against and 5% did not have an opinion.[
In the U.S., surveys have long shown a majority in favor of capital punishment. An ABC News survey in July 2006 found 65 percent in favor of capital punishment, consistent with other polling since 2000. About half the American public says the death penalty is not imposed frequently enough and 60 percent believe it is applied fairly, according to a Gallup poll from May 2006. Yet surveys also show the public is more divided when asked to choose between the death penalty and life without parole, or when dealing with juvenile offenders. Roughly six in 10 tell Gallup they do not believe capital punishment deters murder and majorities believe at least one innocent person has been executed in the past five years.
