Summary: Debating free speech in the wake of Charlie Hebdo; plus, the relevance of impartiality and objectivity in journalism. France has a tradition of satire that shocks and savages - to an extent that would not be tolerated in other so-called liberal democracies. There is nothing that justifies the murder of any journalist or cartoonist over their work, but this is a story in need of explanation. Helping us to do that this week is Padraig Reidy from the campaign group 89up; Anna Reading, a professor at Kings College London; writer and academic Richard Seymour; and Alain Gresh, the editor of Le Monde Diplomatique.
