Hart stood by his work, stating that critics have failed to "engage with the book's larger arguments about the nature of the IRA and the Irish Revolution" and believing they are closed to "a real debate where people concede some things and put forward others or are skeptical about weak points and accept the strong points." Hart's last known interview was in a TG4 Irish language programme on Tom Barry, broadcast in January 2011. The programme had access to eight of nine Chisholm tapes (in total) and questioned Hart's use of anonymous sources and other claims.
