Im sorry that happened to you - I called the police on my neighbour once when he was beating up his wife and they knocked at my door after they had seen them to tell me they were ok - he was a big man and it was scary for a while but thankfully they all moved out - I often wonder if shes ok...
you did the right thing - maybe they wont remember/realise it was you if they had been drinking - I hope things calm down for you

Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
