If evidence is illegally seized by the police, unintentionally, then it will be thrown out of court and not used to prosecute.
- A.
True

The exclusionary rule, which is a legal principle, states that evidence obtained through illegal means should be excluded from trial. However, there are exceptions to this rule, such as the good faith exception, where evidence may still be admissible if the police believed they were acting within the law. Therefore, the statement that illegally seized evidence will always be thrown out of court and not used to prosecute is false.Rate this question:
