Answer: evidence obtained illegally is inadmissible in court
Explanation: The exclusionary rule aims to protect people from using evidence that was gathered against them, in a way that abuses the constitution of the U.S. such as a search and seizure without reasonable cause. This also covers evidence that was collected due to the excluded evidence. For example if someone is recorded in an illegal voice recording and due to what they say, the location of more evidence is found, both the recording and the new evidence cannot be admitted in court.
