But here's a hint, when they call it Deporting the Undocumented: A Cost Assessment[PDF] , instead of saying, as Gillespie does"So How Much Would It Cost to Deport All Those Illegal Immigrants Anyway?," [ Hit and Run, July 10, 2006] then that one word, "undocumented," tells you all you need to know about their attitude to the idea of enforcing the the immigration law. Ed Rubenstein has some contrary facts and figures here:National Data: No-one’s Suggesting Mass Deportation—But It Would Pay For Itself.

Note: Gillespie also links to an Onion infographic with a picture of a very well-built fence.
