I've just reviewed "It Can't Happen Here" by Sinclair Lewis. This book (and the two preceding books In the "Small Change" trilogy) is that story as it might have played out in England. Jo Walton has convincingly described how ordinary people will accept the deprivation of the liberty of others and carry on as if nothing was wrong. Martin Niemöller's "First They Came..." is a poem that describes how the process works, until suddenly it's you who is being arrested because of something someone said about you to someone in authority. A frightening decay of civilisation, conducted in the name of "security".
