What is reasonable doubt for a jury in a sexual assault case?

^9. Penal Code section 1096 defines reasonable doubt as " 'not a mere possible doubt; because everything relating to human affairs is open to some possible or imaginary doubt. It is that state of the case, which, after the entire comparison and consideration of all the evidence, leaves the minds of the jurors in that condition that they cannot say they feel an abiding conviction of the truth of the charge.' "

^10. Purvis, supra, 60 Cal.2d 323 was overruled on other grounds in People v. Morse (1964) 60 Cal.2d 631.
