LAPD officer Joseph Jarrett was enjoying dinner at a restaurant in Los Angeles when he heard screaming from the kitchen.  Through the window he saw a someone holding a knife, so he knew he had to act. Jarrett went into the kitchen and drew his off-duty weapon, and the man wielding the knife stood down and dropped his weapon. Then Jarrett was able to restrain him until authorities arrived.
