In 1973, the An Garda SÃochána, or Irish police, used their gun registration lists and ordered all owners of handguns and centerfire rifles to submit the guns for ballistics testing. The police promised the guns would be returned a few weeks later, after the testing was complete.
Instead, the police simply confiscated all the guns.
In 1998, the signing of the Good Friday Accords finally ended the troubles in Northern Ireland. Over the next several years, PIRA surrendered their weapons, and former members and supporters now participate peacefully in the political process through the Sinn FeinParty. SF is a minor party in the Republic of Ireland, but it is the second-largest party in Northern Ireland.
The Good Friday Accords ended any plausible justification for the police to keep the confiscated guns. Notably, the gun confiscation had never been authorized by the legislature.
