Our final podcast from the MacGill Summer School in Glenties features Europol director Ron Wainwright who talked with Hugh Linehan about continuing threat of terrorism, the adequacy of French authorities' response to the massacre in Nice, and the difficulty of identifying rapidly radicalised lone attackers. Then SDLP leader Colum Eastwood and FG MEP Mairead McGuinness discuss about the political situation in Northern Ireland and the border counties following the Brexit vote. And Hugh also caught up with the man who has made MacGill happen annually for three decades, Joe Mulholland.
