This should be done more often, way more often.

This should be done more often, way more often. This semester I'm giving a course about German foreign policy and my students notice quite often that in a YouTube clip a certain question was asked, but a politician (or spokesperson) never answers it and instead talks about other things. If politicians cannot answer questions and instead want to waste our time, take them off air or at least tell them very clearly that they are wasting everyone's time.
