I want to know the answer to the following question:
What did the exclusionary rule provide for?
All the background I'm provided with is that "Due to the perennial inability of legislatures in the U.S. to enact statutes that would actually force law enforcement officers to respect the constitutional rights of criminal suspects and convicts, the federal judiciary gradually developed the exclusionary rule as a method to enforce such rights.". Is that enough to answer the question?
Answer: yes
