As for the other, tell me, if you go in and talk to an IRS agent regarding an audit, do fourth or fifth amendment protections attach? The answer is - it depends. If you're being deported, is there a right to an attorney? Is the TSA required to notify you of any rights if they find anything in your luggage? Nope. Only when the LEO shows up are they.

The fact is that many Bill of Rights protections only apply where criminal prosecutions are contemplated. For an example of this, INS v. Lopez-Mendoza states that the exclusionary rule doesn't apply to deportation proceedings. And isn't the exclusionary rule a result of the fourth and fifth amendments?
