As a comparison, in Canada, Australia, New Zealand, Latin America, and Western Europe, the death penalty is a controversial issue. However certain cases of mass murder, terrorism, and child murder occasionally cause waves of support for restoration, such as the Robert Pickton case, the Greyhound bus beheading, Port Arthur massacre and Bali bombings, though none of these events or similar events actually caused the death penalty to be re-instated. 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%. The Canadian government currently "has absolutely no plans to reinstate capital punishment." Nonetheless, in a 2011 interview given to Canadian media, Canadian Prime Minister Stephen Harper affirmed his private support for capital punishment by saying, "I personally think there are times where capital punishment is appropriate." According to some polls, as of 2012, 63% of surveyed Canadians believe the death penalty is sometimes appropriate, while 61% said capital punishment is warranted for murder. In Australia, a 2009 poll found that 23% of the public support the death penalty for murder, while a 2014 poll found that 52.5% support the death penalty for fatal terrorist attacks.
