Query: An intense and insightful view of Mexico/US border issues.

A terrific journalist, Sebastian Rotella was the LA Times guy in Mexico, now he's in South America. This is a great read for anyone who wonders what goes on at the border besides guards, people spilling over walls and American teens going to Tijuana to drink. He explores both sides of the fence and scratches the surface to find out what lies beneath.
