The topic was border incursions by members of the Mexican military or facsimiles thereof. Nancy and I have differing views on how such occurrences should be publicized. You can see there is some diversity of opinion among Americans in Mexico.
My first article in the dialogue was ""Are Mexican Soldiers Involved in Border Area Crime?" .
That was followed by Nancy's "Why US and Mexican Officials Downplay Border Incursions".
That in turn was followed by my column entitled "Columnists Debate Candidness in US-Border Issues."
