The gun pic got me thinking of despair at needless deaths in American school shootings and the like. In particular one quote from gun supporter saying that the best solution to a bad man with a gun is a good man with a gun - hence the (ironic) title. So the lyrics went there, and led me to a Dylan-goes-electric musical setting.
