Put aside the illegal aliens for the moment. What about all the US citizens who might use stolen identities? For example, one of your workers disappears and you discover that they walked off with $millions worth of your stuff. You report this grand theft, giving the police the supposed identity. The police later tell you that this person died 3 years before you hired him. For example, you hire somebody who uses a stolen identity to pass your background check. They just got out of prison for beating their previous boss to death. For example, you hire a supposed professional with some sort of certification. They might claim to be a doctor, a Professional Engineer, a lawyer, or a Certified Public Accountant. By identity theft, they convince you that your business can depend on them to meet legal requirements and do competent work. Correct identity is rather important.
