Execution occurs in countries that are both industrialized or otherwise. We seem to be lagging behind 'civilized' countries such as Haiti, Cambodia, Columbia, Mozambique, Turkmenistan, and the Ukraine, which all have laws against execution.
Bosnia-Herzegovina, Brazil, El Salvador, Mexico, and Peru only have the death penalty in effect for exceptional crimes, and crimes commited under military law.
And Turkey, Albania, and the Central African Republic all have the death penalty, but have not actually executed anyone in the past 10 years.
None of the above, are places I'd care to live. Yet they manage to get by without the need for government slaughter. Unlike, say, the Russian Federation, China, Japan, Myanmar, Iraq, and Somalia.
And in the really elite circle are the six countries that have executed inmates under the age of 18 since 1990. Drum roll please....
Iran, Nigeria, Pakistan, Saudi Arabia, Yemen, and--you guessed it--the good 'ol U S of A.
