You're referring to the side of the story told by the police and jail officials.
In criminal law, their side of the story comes out as their testimony in the trial. In criminal defense practices, their testimony is known as "testilying". The juries eat it up-- after all, we should trust the cops, right?
The fact that there is a "second side" does not mean that the second side is true, valid, or not-fabricated for the convenience of the police.
Sure there's a second side. I'm sure there's a very valid reason to stomp on one's hands and keep one in 12-hour solitary confinement after roughing up, interjected with strip searches and various abuse - as a punishment for calling 911. And she shouldn't have worn that outfit if she wasn't looking for trouble.
