The NSA sits at the nexus of violations of both the Fourth and Fifth Amendments with a legal dodge called Parallel Construction.
Parallel Construction is a technique used by law enforcement to hide the fact that evidence in a criminal case originated with the NSA. In its simplest form, the NSA collects information showing say a Mr. Anderson committed a crime. This happens most commonly in drug cases. The conclusive information is passed to the Drug Enforcement Agency (DEA), who then works backwards from the conclusion to create an independent, "legal" body of evidence to use against Mr. Anderson.
Example: an NSA email intercept shows our Mr. Anderson received a Fedex package with drugs, which he hid under his bed. The DEA takes this info, and gets a search warrant for the Fedex data, which leads them to Mr. Anderson's apartment. A new legal warrant authorizes a search, and agents "find" the drugs under the bed right where the NSA said they were in the first place.
Some may call this little more than illegal evidence laundering.
