France has marked 10 years since an Islamist attack on the Charlie Hebdo satirical newspaper that shocked the country and led to fierce debate about freedom of expression and religion. FRANCE 24's Sharon Gaffney speaks to Jacob Mchangama, founder of 'The Future of Free Speech' think tank and research professor at Vanderbilt University. He says that terrorism has curtailed freedom of expression, adding that France's "schizophrenic" approach helps erode the culture of free speech.
