Wal-Mart and Aliens

You would think that a company that'’s perpetually under the microscope like Wal-Mart would be very careful about this sort of thing. At a certain point saying you didn't hire them your contractor did just won'’t wash. Sometimes you just have to take responsibility. If Wal-Mart stipulated and insisted on its contractors only using legal labor, they would. Do you think they'd take a chance on losing such a huge contract?
