I agree it's possible. The dissidents are fewer in number than many think. More joined them fresh than from the ranks of the Provo's. A good few are guys who for one reason or another had old scores to settle with the Provo's and felt they were now in a strong position.

The Special Branch and D.M.S.U. are still in place with little or nothing to do, so they know everyone of them and probably have cameras trained on their homes.

Be careful entering another North of Ireland subject,you will end up getting tormented by mudcat's resident historian on Irish affairs !
