d. people are entitled to freedom of speech.

c. A person is innocent until proven guilty.

Explanation:

The Jews had "innocent until proven guilty" as a principle, since the law of Moses required them to have a justice system based on proofs.

The Witnesses stood next to someone accused, requiring to submit evidence, as stated in Deuteronomy.

A single witness was not enough, and judges were to carry a careful investigation to solve the case.

Deuteronomy 19:15 states:

You cannot convict anyone of a crime or sin on the word of one witness. You need two or three witnesses to make a case. If a hostile witness stands to accuse someone of a wrong, then both parties involved in the quarrel must stand in the Presence of God before the priests and judges who are in the office at that time. The judges must conduct a careful investigation

In case someone falsely blamed another one, punishment followed:

if the witness turns out to be a false witness and has lied against his fellow Israelite, give him the same medicine he intended for the other party. Clean the polluting evil from your company.
