"I want to remember the terrible risks people took to escape. We have seen pictures of these people on our television screens, crammed into fishing boats, clinging to the sides of canoes or even crudely lashed bits of wood. I hadn't seen any such pictures when I left Zanzibar and I don't suppose many of the ones we watch staring back at us in terror have either. People take such risks because they fear for their lives. It is an unarguable, terrible thing to be so afraid. I want to remember that, and to remind anyone who is inclined to forget or who has not got around to imagining what it might feel like."
