(citations omitted) The further requirement of 'probable cause' instructs the magistrate that baseless searches shall not proceed. U.S. v. U.S. District Court, 407 U.S. at 316.
The Fourth Amendment, accordingly, was adopted to assure that Executive abuses of the power to search would not continue in our new nation.
Justice White wrote in 1984 in United States v.

Id. at 714-715. Karo is consistent with Katz where Justice Stewart held that:
