The government’s firearms buyback programme is in turmoil and police minister Stuart Nash has been called on to resign after a data breach of the buyback website revealed full contact details, firearm licence numbers and bank address details of more than 37,000 gun owners. The breach was revealed by the Council of Licenced Firearms Owners (COLFO) which issued a statement at 12:23pm saying it had just learnt that information on 70,000 firearm hand-in notifications were accessible to users of the buyback web site.
