Answer:
c.a trial by a jury of one’s peers and double jeopardy
Explanation:
The two elements of the United States’s legal system that can be traced to Roman law is "a trial by a jury of one’s peers and double jeopardy."
This is evident in the fact that in the Roman republic, the trial by a jury of one's peers is well established whereby citizens are judged by their fellow citizens rather than the Emperor or King.
Also, double jeopardy is established in roman law that a person declared acquittal by a judge in a criminal case is exempted from further proceedings under the same charges.
During the ensuing decades, the abolitionist movement grew in Northern states, and Congress regulated the expansion of slavery as new states were admitted to the Union. Britain banned the importation of African slaves in its colonies in 1807 and abolished slavery in the British Empire in 1833.
The case <em>Miranda v. Arizona (1966)</em> was a landmark decision of the Supreme Court in which the court established that prosecutors cannot use a person's statements made in response to interrogation in police custody as evidence at their trial, unless the person was informed of what is known as "Miranda warning," but voluntarily waived these rights.
A "Miranda warning" is an explanation given to people arrested that informs them of the right to consult with an attorney before and during questioning. It also informs them of the right against self-incrimination before police questioning. The court's ruling protect those accused of a crime because it prevents them from incriminating themselves. It also reminds them of the importance of an attorney for achieving a successful trial.
