Madam, – If we ever needed an example of a double standard in the application of criminal law in our Irish society it is how a mother of five is sentenced to 30 days in jail for failing to ensure her child went to school (Home News, May 7th) and how other highly irresponsible individuals who through their criminal wheeling and dealing have created havoc in our society but will never see the inside of Mountjoy Jail. – Yours, etc,
