EDIT: I hate to post links from the UK Daily Mail but they have an article on this: http://www.dailymail.co.uk/home/moslive/article-2219618/Will...
EDIT 2: From http://www.politifact.com/punditfact/statements/2015/feb/23/... : ""I think countries that small are just not comparable," Wagner said, adding that his group’s 2014 States of Incarceration report filtered out countries with less than a half-million residents." ... "Only Seychelles technically has a higher incarceration rate than the United States. But experts said it’s an outlier because of its miniscule size and largely should be disregarded."
