At the time she mentioned that she was going to call the police and say that “there was an African-American man threatening (her) life”, any filming from that point forward is simply the only protection the man has against the woman’s word; I cannot imagine that in our post - Blasey-Ford world, even a woman would fault him for this.
Excellent point. She could have accused him of God knows what. The very fact that she was willing to call the police because he was filming her and offered her dog a treat, willing to claim that he'd threatened her, shows she was perfectly capable of accusing him of assault.
