The killing of Michel Brown, a black teenager, on August 5, in Ferguson, a suburb of St Louis, Missouri, has received worldwide attention. He was shot by a white police officer, Darren Wilson. A grand jury has decided that Wilson has no charge to answer. Nothing to see, so move on. But, stop, there is a fleeting glimpse of ourselves in that mirror.
Part of the Irish identity abroad was opposition to people of darker colour. This is not a Frankenstein mutation, triggered by emigration. It is rooted here, and it is still here now.
