Communities and police repairing their relationship

I don't think communities and police can repair their broken relationships because the police are doing horrible stuff to people. They are killing innocent young black men. They're beating people and hurting them. They huras people. They people up sometimes for no reasons. Then people are without their family members for life or years. They'll only get to see them through a glass box. But you never know they may be able to fix their relationships. It just takes for everyone to forgive one another. Then try to fix the community together.
