Or streetcars, as they call them in America. This is silent film of them in Washington DC in the early 1950s. These have long gone, but there is now a plan for a new tram system there.
Let us be clear: Julian Assange is an arrogant, self-important twat. But even arrogant twats have the right not to be extradited on trumped-up charges. Does anyone seriously believe in the accusations of rape? And what on earth is Sweden playing at? It is almost the last country one expects to see doing the USA's dirty work for it.
I don't of course buy the argument that the Wikileaks operation is morally justified on freedom of information grounds. Not all information can or should be in the public domain. Certainly we ought to be told in general terms what governments are doing in our names, but it is remarkably naive to think that that means every piece of paper can be published.
But there does seem to be an element of "shoot the messenger" in the reaction of our various dear leaders, a sort of mixture of outrage and panic. The clearly guilty party is the US government employee who leaked the stuff in the first place, rather more than Wikileaks for broadcasting it.
