William O. Douglas,
Zap v. United States — Dissent
“ As to what is to be taken, nothing is left to the discretion of the officers executing the warrant.' If where a search instituted under the legal process of a warrant, which also authorizes seizure, does not permit seizure of articles other than those specified, statutory and contractual authority merely to search cannot be considered sufficient to grant that power. The Government relies on a doctrine quite inapposite here. If, in the course of a valid search, materials are uncovered, the very possession or concealment of which is a crime, they may be seized. ”
