The silencing of Stephen Daisley has nagged away at journalism in Scotland for months. His employer, STV, holds the ITV licences for central and northern Scotland, and is staying very quiet. The Scottish National Party rolls around like a drunk who has won a bar fight. Its politicians and its claque of Twitter trolls celebrate their power to bully and tell direct lies about the journalist they have humiliated. The BBC endorses them. The National Union of Journalists supports them. Everyone behaves as if they are living in a one-party state.
