We are, a lot of the time, baffled by the news we see on the front pages of our newspapers, often because the stories are complex, and we missed the beginning of them anyway. (How far back do we have to go to find the roots of the Euro crisis? To 2008? 1999, when the currency came into being? 1992? 1945?) That is one of the reasons why natural disasters and murders and cases involving missing children become so involving: we understand them.
