Actually, they did.
No they didn't. That's the point. The exclusionary rule is an invention of the judges. It wasn't inventied until the early 1900's. It wasn't applied to the states until 1949.
Many believe that it should be abolished. That includes the current Chief Justice.
When you think of it, they're right. Who does the exclusionary rule punish? The cops? No. It punishes the ordinary, law-abiding citizen because it turns criminals back on the street to commit more crimes.
