while this is true, it's perfectly legal to issue a subpoena or some other court order to collect evidence of a crime or a plan of future criminal activity.
That court order is called a "warrant". Subpoenas are also issued by the court or its officers, but only in conjunction with a pending court case. The main point is that the court issues both of those documents, not an executive agency under its own authority. Also, note that the Fourth Amendment covers "persons, houses, papers, and effects", not just "homes or property".

Probably not a good idea to impugn the education of another while conflating plurals and possessives in the same sentence. Yeah, I'm being a grammar Nazi on purpose, but that's just because you could have made your point in a civil manner.
