Sir, - I had recently lost some of my long-standing admiration for Irish Times journalism. Three articles in the past few days have, I am pleased to say, restored my faith completely.Fintan O'Toole's column on President Clinton and public responsibility (Opinion, January 30th) Dick Grogan's article of the same day on Bloody Sunday, Dick Walsh's column on Saturday day on the same subject have left me searching for superlatives at the extraordinary quality that you are capable of. My congratulations. - Yours, etc.,Patrick NolanDaisy Terrace,Waterford.
