I think it's scary that terrorists can kill that many people in an HIC's CAPITAL in Europe, especially a country like France which has an army police (they have 2 types of police, a UK sort of police and an army one I think, correct me if i'm wrong plz) and then get away with it, although I do agree that we should keep a calm head about it, I think that Europe needs to do something because if terrosist can do that in Paris, who says they can't do it in London, Madrid, Berlin etc.?
