Communities have a larger role to play in the ending of domestic violence. This is because as individuals, we can attempt to effect change but change usually only happens when multiple individuals bind together and speak with one voice. This is not unlike protests against the government. Take Sudan last year for example, for years select individuals had been speaking out against the Government and have found themselves arrested or missing. When the nation came out in it's thousands and marched and demanded change, the regime was overthrown. This shows that when the community comes out as one and speak against societal ills like Domestic violence, it has a better chance of being stopped.
Another way to look at it is that the Community usually has various social norms that are generally expected of members, if the community categorically classify Domestic Violence as a violation of norms then there is a better chance of ending it.
