How has the court interpreted instruction on involuntary manslaughter?

The error was harmless, however, for the jury was otherwise instructed that the [783 P.2d 224] prosecution had the burden of proving all the elements of the crime [49 Cal.3d 1196] and that the jury was required to find beyond a reasonable doubt that defendant possessed the necessary mental states required in the crime of murder. There is no reasonable probability that a result more favorable to defendant would have been reached had the correct instruction been given. (People v. Watson (1956) 46 Cal.2d 818, 836, 299 P.2d 243.)
