William J. Brennan, Jr., Horton v. California — Dissenting Opinion
“ But to the individual whose possessory interest has been invaded, it matters not why the police officer decided to omit a particular item from his application for a search warrant. When an officer with probable cause to seize an item fails to mention that item in his application for a search warrant-for whatever reason-and then seizes the item anyway, his conduct is per se unreasonable. Suppression of the evidence so seized will encourage officers to be more precise and complete in future warrant applications. ”
