This week and every week television in this country brings us the stories and issues that concern us-the argument, the evidence, the examination. We listen and we watch-sometimes we switch off or ever-and then we make up our minds. But nearly all the coverage is seen through our eyes. Elsewhere in Europe the same process goes on-but there the view may be quite different.
