Can it only be a week? Not often in my life have I spent a whole day following a news media feed. The first time was when with friends in London I listened to the American Armed Forces Radio Network reporting on the events in Dallas in 1963.
Then there was the coverage of the 2001 disaster of the World Trade Center attack in New York. The inevitable ripostes saw troops storming across Iraq, with BBC journalists reporting live from the front lines.
And now Charlie Hebdo, with consequences hard to imagine. So terribly sad.
