Pointing isn’t an element of brandishing in California.
Cal. Penal Code section 417(a)(1) describes “basic” brandishing:
Every person who, except in self-defense, in the presence of any other person, draws or exhibits any deadly weapon whatsoever, other than a firearm, in a rude, angry, or threatening manner, or who in any manner, unlawfully uses a deadly weapon other than a firearm in any fight or quarrel is guilty of a misdemeanor, punishable by imprisonment in a county jail for not less than 30 days.
So, just waving a gun around in a threatening way is good enough.
Actually, doing more research, the rent-a-cop’s crime appears could be a felony per Penal Code section 417.3:
Every person who, except in self-defense, in the presence of any other person who is an occupant of a motor vehicle proceeding on a public street or highway, draws or exhibits any firearm, whether loaded or unloaded, in a threatening manner against another person in such a way as to cause a reasonable person apprehension or fear of bodily harm is guilty of a felony punishable by imprisonment pursuant to subdivision (h) of Section 1170 for 16 months or two or three years or by imprisonment for 16 months or two or three years and a three thousand dollar ($3,000) fine.
