She’s the assistant manager so had job related reason to be there and interacting with the residents. I however would have driven away if it was possible.
The ‘I carry a weapon’ attitude is not particular to cops.
Just another one of life’s teachable moments. “Don’t go to a gunfight carrying a knife”.
Some of the citizens won't run away, even if they aren't armed. Cowardice is distasteful to some.
