The fourth amendment is about protecting individuals from government searches. It says nothing about admissibility in court, despite your implication.

>The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

He/She is exactly right – the fourth amendment is highly relevant even after a search has taken place.

Ah, religious metaphors. The fourth amendment is relevant in many instances, however it explicitly mentions preventing searches and says nothing about what to do if a government official decides to evade their restrictions.
