You need to be able to have rock hard evidence to put a criminal away depending on the jury and what they think but in most cases you need evidence that can for sure put them away.
Answer:
A. U.S. Circuit Court of Appeals
Explanation:
A is the answer. B is incorrect because the U.S. Circuit Courts (not to be confused with the CIRCUIT COURT OF APPEALS) were the direct predecessor to the Circuit Court of Appeals. C is incorrect because the question is asking about the federal court system, not the Floridian court system. D is incorrect because there is no such thing as U.S. District Courts of Appeals.
