To obtain a search warrant or arrest warrant, the law enforcement officer must demonstrate probable cause that a search or seizure is justified. An authority, usually a magistrate, will consider the totality of circumstances and determine whether to issue the warrant. [1]

I agree to your statement, if there is no search warrant. But in this case an authority already decided that the search is justified. What use are search warrants then if they can all be refused?

I understand, that even a magistrate or whatever can make errors. But if this happens a lot, the consequence will be, that search warrants are issued without second thought and the person/company affected by the search should always deny it first.

I'm all for privacy and defending individual rights, but cases like this make a farce out of court orders and the whole jurisdictional process.
