Final answer:
The best choice that illustrates the principle of excluding evidence obtained illegally is (D), where Kuttner's admission of setting illegal traps cannot be used against him due to the officer's trespassing.
Step-by-step explanation:
The principle illustrated by the argument presented involves the inadmissibility of evidence obtained through illegal means, protecting the rights of the individual against actions taken on the basis of such evidence. This principle relates to legal and constitutional provisions that ensure fair treatment under the law and exclude unlawfully obtained evidence, often referred to as fruit of the poisonous tree. The case of Miranda v. Arizona is a clear example where the Supreme Court ruled that evidence gained from police interrogation without advising the suspect of their rights is inadmissible because it violates constitutional protections against self-incrimination.
The best choice that illustrates this principle is (D), where Kuttner admitted to setting illegal animal traps after being discovered by a conservation officer who was trespassing. Despite the admission, the conservation officer cannot justifiably punish Kuttner because the evidence was obtained illegally.
