Syllabus

1. An affidavit which merely asserts affiant's belief in the truth of statements made in the affidavit of another, to which it refers, is insufficient to support the issuance of a search warrant. P. 287 U. S. 127.

2. An affidavit setting forth facts tending to show that the dwelling described was used as a manufactory of intoxicating liquors, but which states no facts from which a sale, on or off the premises, necessarily is to be inferred, is insufficient to support the issuance of a search warrant. National Prohibition Act, Title II, § 25; Act of June 15, 1917, Title XI, § 6. P. 287 U. S. 128.

3. The guaranties of the Fourth Amendment are to be liberally construed to prevent impairment of the protection extended. Id.
