Truly, we are not far from the time when the authorities could have sex with your wife, and you could do nothing but file a grievance. Tell me what would happen if a police officers showed up at your door, asked for entrance, and you told him NO? He wants in, he kicks the door in, saying that there was a "disturbance". He handcuffs the husband, takes the wife into the back room for "questioning". Comes out after "hearing" what he wanted, he arrests the husband for Domestic Violence. Of course since the husband and wife can not legally talk to one another, because of the charges pending, the wife goes to the police station to tell her story. No one believes her, because of course "those type of people" that are prone to incidents of DV, will tell any story to "save their skin". The husband is automatically guilty, and will have to pay fines, and go to classes, no matter the outcome of a trial. For this couple to mend their lives, will they not usually drop the matter?
You see, we are very close to a place that people in the USSR, or many other tyrannical societies have lived in. The police can do what they will, as long as it is not on videotape. When caught they are put on paid leave, given raises, or transferred to another district.
Your scenario is not far from being plausible. I see if the victim complains then they would even be further harassed. For example, a “new” drug charge. Easy enough to do. Pull one over, plant the drugs and do an arrest. In no shape, form or manner does this ruling do anything but hinder/hurt real law enforcement officers. The separation between civilians and the police will even widen. Maybe to levels never seen before. We truly are living in dangerous and frightening times.
