Nigerian Lawmakers, 'Calexit' Hashtag, Dark Tourism

Available for over a year

Two statistics from Nigeria: do lawmakers really get paid $1.7 m – much more than the American President and does eating yams give Yoruba communities a record number of twins? We talk to the fact checkers at Africa Check. We investigate connections between Moscow and “Calexit” groups that want to break up the United States. Also, the list of "sexual predator" professors that has sparked an online debate in India. Millions of people every year visit sites of death, tragedy and destruction, from nuclear disaster zones to genocide memorials. Is it an effort to understand the darker parts of our history, or are we just indulging our morbid curiosity? Mary-Ann Ochota investigates dark tourism.
