PHOENIX (AP) - Francisco Cantu said he joined the Border Patrol at age 23 to get an on-the-ground education in international relations.
Now 32, he says he didn't expect his new memoir examining some of the agency's uglier aspects would spark protests by far-left groups denouncing him for the work and forcing him to cancel some talks promoting the book.
He said he agrees with much of the criticism from the left, even though it caught him off guard.
Cantu said he wrote "The Line Becomes a River: Dispatches from the Border" to make sense of his time with the patrol and to share his experiences and self-examination with readers.
He's scheduled to appear this weekend at the Tucson Festival of Books.
