I've worked with abused women. Unfortunately, most police departments won't do jack for a potential domestic abuse victim. She can call and tell them she fears for her safety, but until he threatens her with physical harm, or actually attacks her, they won't do anything. If he does do those things, she'll then have to go to great lengths to prove it. And then, for many victims, once they do get attacked, they get shamed for not looking out for themselves. "Well, you knew he was scary. Why didn't you get a gun? Carry mace? Get a restraining order?" It's absolutely fucking infuriating.
