Op-ed: If we can put chips in our pets, why not in freed detainees?

Last week's op-ed segment dealt with whether exchanging five Taliban prisoners for Sgt. Bowe Bergdahl was prudent. This week, we explore an entirely different angle of that same story: Should we, and did we, implant microchips in the five prisoners before they left Guantanamo Bay? Medical ethicist Arthur Caplan says if we didn't this time, it's an inevitability that we will in the future.
