How has the exclusion of evidence in a civil case concerning the cooperation of a witness in the trial of a defendant in an assault case been interpreted?

13 Even were our conclusion otherwise, however, the exclusion was hardly prejudicial. The basic facts concerning Harvey's cooperation were presented to the jury. Moreover, we have previously indicated that the evidence establishing Harvey committed the shootings is strong and generally unrebutted. (See ante, p. 918.) It is not reasonably probable a different result would have been reached had the evidence been admitted. (See People v. Watson, supra, 46 Cal.2d at p. 836, 299 P.2d 243.)
