While Dr. Montgomery's detention in Zimbabwe, particularly the way the matter has subsequently been handled, is lamentable, it could all have been easily avoided. As a 20+ year resident of Zimbabwe, I can attest to the fact that - because of pressing shortages of physicians - the country has been victimized by fraudulent doctors on numerous occasions in the past. Patients have died as a result. For this reason, the previous approach based on good will was abandoned, and formal procedures were adopted to establish medical credentials and accreditation.
Although their motives were undoubtedly of the best, it was blatantly naive of Dr. Montgomery's preparation to assume that an American doctor can practice medicine anywhere in the world just because he/she has had a long career in the United States. After all, we do not even allow physicians to practice across state lines here. The most rudimentary prior checking would have confirmed the steps necessary to allow a foreign missionary medical team to operate in Zimbabwe.
