So this news comes as a ray of sunshine in the darkness. New Mexico recently abolished the death penalty, joining only a handful of US states (14 to be exact) which do not have death penalty. The last state to abolish death penalty was New Jersey, a few years ago.
In addition, Colorado, Kansas, Maryland and Montana are considering abolishing death penalty. If Montana does abolish death penalty, that will make the question of Canadian government intervening on behalf of the Canadian on death row moot.
It has not all been good news on this front, a few years New York reinstituted the death penalty (when they had a Republican governor, Pataki). Even today, most of the US population is covered by the death penalty; the states who have abolished death penalty are smaller states. Bigger states such as New York, California, Texas have death penalty (Texas of course, executes more criminals than any other state).
While worldwide there has been considerable progress towards abolishing death penalty (all the countries in the developed world, with the exception of USA and Japan, have abolished death penalty), in USA the progress has been slow and painful. The strong influence of religion is responsible for that (eye for an eye, tooth for a tooth, that kind of thing).
Anyway, as an opponent of death penalty, I will take any victory, however small. So congratulations, New Mexico, for entering the 21st century.
