Madam, - There are many demands for clarity from the IRA that there will be an end to violence, which would be most welcome. But it seems strange that in recent weeks it has been established that security forces in the North colluded with loyalist terrorist groups in the murder of Catholics. Is there any chance we might get some form of clarification that this has ended? - Yours, etc.,
JOHN WHITMORE, Beaumont, Dublin 9.
