The greatest day became one of the darkest days. How could this happen? One moment there was a tickertape explosion, the sky thick with plumes of red smoke, the new smell of celebration.
Then, in the next step, came the piercing shrill of screams, flashing blue lights and the overwhelming sense of horror. They had descended in their hundreds of thousands in celebration. They left having witnessed a tragedy, knowing a city was in mourning.
We don’t know why a lone man ploughed into revellers in his car, but we do know the impact it has had, the lives that have been wrecked and the nightmare that has been inflicted.
