Charlie Hebdo

Looking beyond the headlines: correspondents with insight and analysis consider: Charlie Hebdo and the way life used to be in France; the rallies in Germany for and against the influence of Islam on society there and the arguments over free speech in Turkey. Also in this edition one correspondent, leaving Mexico, pays tribute to the country's brave mothers while another, visiting Antarctica, wonders if tourists should be allowed even to set foot in this, the earth's last great unspoiled wilderness.
