After graduation, Munro was a criminal prosecutor in Edinburgh for several years until joining a private law firm, where he specialised in litigation.
Munro later returned to Dallas Theological Seminary to earn a Doctor of Ministry degree in 1993 with a dissertation in pastoral leadership.
During that time, he was a pastor to professional American football players Craig Wolfley, Mike Webster and Tunch Ilkin.
Without publicly providing details, church elders placed him on paid leave, pending the outcome of an external investigation, and international media ministry Back to the Bible terminated its relationship with Munro over accusations of similar misconduct.
[7][8] Munro currently hosts an internationally syndicated daily and weekly 25-minute radio program called The Verdict, in addition to his pastoral duties.
