Radio and TV pose a clear and present danger. We don't know who the people are who call in. If the host cooperates or gives hints, this anonymous format can pose an immediate risk. Radio waves are a limited resource that belongs to the whole people, and they have exclusivity (that is to say, when one person is using them, others cannot).
廣播電視有立即、明顯的危險，打電話進來的人我們不知道他是誰，這種匿名的傳播方式，如果再受到主持人附和或者暗示，就可能發生立即危險。
