If he was “polite and asked her numerous times just to” take her clothes off,
would that be OK?
That's an asinine comparison, and if you don't know that, you are beyond help. In any situation where safety is an issue, the police have a right to take reasonable steps to secure the scene. It doesn't matter that she was on her property - she was close enough to the cops to make her a potential threat. If the cops come into your home to ask you some questions, they may ask you to not go into another room without an officer present - to prevent you from coming back with a gun. That is not unreasonable.
She was asked to move back or go inside to ameliorate that perceived threat. She refused. Should she have been arrested? Probably not, but she probably should have been taken aside by one of the officers and her movements restricted to insure the safety of the officers until they were done with their arrest of the suspect.
