For five years Francisco Cantú was a patrol agent on the US–Mexico border, a deadly crossroads for human trafficking and drug smuggling. Hailed by Vulture as among the most exciting releases for 2018, Francisco’s memoir, The Line Becomes a River, details how he quit his job, then saw a fuller picture emerge after an undocumented friend was detained. A Fulbright scholar whose work has appeared on This American Life and in n+1, Francisco speaks to Wheeler Centre Director Michael Williams about “the ways which we normalise violence and dehumanise migrants as individuals and as a society.”
