She threw that in to get the police to come. She thought it sounded good. But even more she was trying to intimidate Mr Cooper. She had no need to call the police at all. Put on the leash, walk away, obey the rules of the bird sanctuary.
I fully agree and have no sympathy for her. I should have said that in my first comment. My point was that the consequences of the call were determined by her mention of his race and not by the call per se.
