Seems like she was at least 10 feet away. Not sure why the police were afraid.
Looks like this should have been a "no call" on the police part.
Ignore her.
The cop was not afraid. He kept saying "I don't feel safe...." which a key phrase (I assume) for authorizing him to do what he did. It's like saying "I felt my life was in danger." after a gun fight to establish a need for self defense. He was basically annoyed by her video taping and gave himself a procedural excuse to do what he did.
