Huge concertina wire coils and tall, monochrome walls command my attention as I walk through a locked metal gate and out into the prison courtyard. A thick bank of clouds over southern Santa Fe County intensifies the cloistered feel hanging over the Penitentiary of New Mexico, the state’s only Level-6 prison. As I leave the courtyard and return inside, I’m focused on the nearly silent clicking as my colleague takes photos of an empty day room and the sliver-like cells surrounding it for a yet-to-publish story months in the making. But for a moment, something invisible — if it’s even there — distracts me. What if COVID-19 got into a place like this?
