3 employers were fined in 2004 for hiring illegal aliens, I'd say we need alot more "interior enforcement."
DHS will be getting right on this. (Ha!) From post 8:
Workplace Enforcement: DHS will implement an employer self-compliance program that will link government and business in a united effort to reduce the employment of unauthorized aliens in specific industries.
That may smell like B.S. but I'm sure it isn't. /sarc
