Jurors Asking Questions

In recent months the case of The State of Arizona v. Arias, raised an interesting question:  “I thought only the lawyers can ask questions; how can jurors be allowed to question a witness (in the Arias case, the defendant)?”

Brief facts for context:  Jody Arias was charged with murdering her boyfriend Travis Alexander.  Arias plead not guilty and provided a defense of “self-defense.”   Although she had a Fifth Amendment Right to “remain silent,” Arias took the stand in her own defense.
