How did Drumgoole know...
...Frank Leone was in the process of serving his time at Norwood (the minimum security prison in the beginning of the film) when the guards from Gateway ransacked Leone's minimum security prison cell in the middle of the night & took custody of him? How did Drumgoole know where to locate Leone during the time he was on parole? Leone did pay his debt to society by the time Drumgoole caught up with him.
