It is true that evidence from an illegal wiretap cannot be used as
evidence in court; this is called the Exclusionary Rule.  While the ER
has been weakened in the last decade, it still basically holds.
Unfortunately, that is not where the main threat lies.

Exploratory wiretaps, illegally made and whose evidence is not
directly admissible, provide information that may lead investigators
to other information.  This secondary information _is_ admissible.

It would be a wonderful if the ER were strengthened so that all
evidence which resulted from an illegal search _and all of its
subsidiaries_ were conidered tainted.  That battle, however, is a much
longer one to fight.

Even in that situation, though, the defense would have to prove that
an unauthorized wiretap took place.
