The Tortilla Curtain by T. C. Boyle is a novel about what it is like to live in LA as an undocumented person. Before condemning those who cross into the US from south of the border, one should try to put oneself in their worn out shoes. If Donald Trump succeeds in building his wall, we will need to give it a name and I suggest that Tortilla Curtain is as good a name as any other. After all the wall between East and West was called the Iron Curtain. And I suggest that it will not be an effective wall unless we are willing to shoot to kill as the border guards were on the Iron Curtain.
