Vigorous democratic debate about death penalty is healthy
In the US, at the national and state levels, we have a vigorous democratic debate over the death penalty, sometimes expanding it and sometimes contracting it.
In every case, though, we do it after free and open debate.
That, however, is not good enough for death-penalty opponents, who can't get what they want in the US.
They too have gone international, using the UN's "human rights" bodies to repeatedly condemn the death penalty. In effect, death-penalty opponents are trying to mobilize international public opinion against the prevailing majority view within the US.
