I want to end a friendship because they involved the police in a personal dispute.
Have you talked to the friend about the incident? How did the friend react?
Yes, I told the friend about my feelings and they said it would never happen again. I still can't trust them.
Typically it's okay to be upset with a friend calling the police on you. Especially if you're a minority, that could get you killed in some countries.
I don't like people who involve the police. I am a vigilante who takes the law into my own hands.
Being a vigilante isn't a good thing. You aren't trained nor equipped to handle the law so leave it to the people who are.
