13-117. Defendant as witness; no comment on failure to testify
A. A defendant in a criminal action or proceeding shall not be compelled to be a witness against himself, but may be a witness in his own behalf. If he offers himself as a witness in his own behalf, he may be cross-examined to the same extent and subject to the same rules as any other witness.
B. The defendant's neglect or refusal to be a witness in his own behalf shall not in any manner prejudice him, or be used against him on the trial or proceedings.
