Sir, - I must protest at the inclusion by Catriona Ruane (Opinion, November 7th), of the Birmingham Six and Guilford Four in her article on the so-called Columbia Three. Lest we forget, the former are wholly innocent of any association with Sinn FΘin/IRA whose atrocities in Britain preceded their incarceration there. - Yours, etc.,
J.A. Campbell, Cowper Village, Dublin 6.
