What’s the importance of Steagald v United States? And do you agree with the decision?

The decision of the Supreme Court on Steagald v United States (1981) established that according to the Fourth Amendment, police officers can´t search for a suspect in a third party´s property without getting a search warrant first.

Explanation:

According to the Supreme Court, the search carried in the house of the petitioner, Gary Keith Steagald, which was conducted only with an arrest warrant for Ricky Lyons, and led to Steagald´s arrest, was a violation of the exclusionary rule stated in the Fourth Amendment that protects all citizens from illegal searches and seizures. I do agree with this decision because any effort to apprehend a suspect should never infringe nor his or a third party´s constitutional rights.

no i don't think so.
