I'd be quite happy with due process enforcement of existing immigration laws.
Federal & state indictments of employers hiring Illegals, followed by aggressive but fair prosecution in the appropriate jurisdictions. If guilty, meaningful punishments as proscribed by law to be meted out - no slaps on the wrist.
Agreed?
Show me your papers please? What happened to the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated??
