Guns are for protection not threats

Why do people who works at metro make it a habit of threatening people with a guy and nothing happens to them.. Who is supposed to protect us If an employer by metro pulls a gun on you and when you report it that person says ure bipolar and makeup all kind of stories.. I'm a victim and I've been scared for a long time but the trauma I went through I need justice for that metro police in pta failed me when a complaint was laid and lies were said at the police station that took the gun and after that another incident happened I was threatened with a gun again by the same person I trusted as my husband..just because a person have a gun for work purpose dissent mean you have to use it to threaten another person fir personal reasons.. This is not fair at all some people don't deserve to be employed at such department wereby they use guns with such a temper. I couldn't have been dead now as nothing that makes sense was ever done and the person still working as an officer
