“ Surely it is fair to say that the lower courts and prosecutors have a right to proceed on the assumption, on the basis of controlling decisions, that whether or not a search is 'unreasonable' turns on the circumstances presented by a particular situation, as a matter of substantive determination. On that test, I find it very difficult to conclude that a police officer may not deem adequate the authorization of a landlord to enter his house without a search warrant where he has solid ground for believing that his lessee is utilizing the house as an illegal distillery. ”

“ Since searches and seizures play such a frequent role in federal criminal trials, it is most important that the law on searches and seizures by which prosecutors and trial judges are to be guided should be as clear and unconfusing as the nature of the subject matter permits. The course of true law pertaining to searches and seizures, as enunciated here, has not-to put it mildly-run smooth. ”
