Before a search warrant can issue probable cause must be shoval supported by affidavit stating sufficient facts that shall justify the magistrate that suspicion is well founded. The mere expression of an opinion under oath is no ground for issuing a search warrant.21

The constitution of Illinois provides that no warrant shall issue without probable cause, supported by affidavit particularly describing the place to be searched and the person or things to be seized.22

A search warrant which describes the premises authorized to be searched does not authorize the search of another building on an adjoining lot, though connected by a passage way.23

But the law which forbids unreasonable search and seizure of articles does not include counterfeit coin, lottery tickets, gambling implements or other things which the law forbids one having in his possession.24
