No, the judge told them they were allowed to do it. The act of doing it is what violated the fourth amendment. If they hadn't acted on the warrant, the fourth amendment wouldn't have been violated. The judge was _wrong_, but the police are the ones that violated the amendment.

“No warrants shall issue, but upon probable cause, … and particularly describing the place to be searched, and the persons or things to be seized.”

Judge Magit violated the amendment by issuing the warrant.
