He is an ex-officer, and every time I would report him or charge him with an assault, would go nowhere. I survived a lot worse than just corruption in the police force, but that is my life story, I am not afraid of anyone but God.
Corruption is everywhere, any illusion that corruption is much less here than other places is not reality.
As your other half is an ex-officer, you need to be very clear when you approach the police. Present evidence that are far and above beyond reasonable doubt. Objective evidence without the need for context or situational information. It would be very very rare for such a case to occur and linking up with advocacy groups for support and action would likely be more helpful rather than seeking validation and procedural justice from police.
