This Friday marks the fifth anniversary of the Paris terror attacks, in which 130 people were killed. The last few weeks have seen more bloodshed, with attacks in the Paris region, in Nice and in the Austrian capital Vienna. European leaders are looking for solutions: ways to stop hate being preached, broadcast and acted upon, while defending individual freedoms of speech and of conscience. In our debate we ask two leading members of the European Parliament, from France and from Austria, what they believe should be done.
