The main reason for this book is for the unjustice part. Nick has assulter his girl friend. He had recieved a court date where he got a restraining order and a mandatory class. If i saw this I wouldnt do much about it unless it got real bad. The only evidence one could have is pictures, videos, or marks on the victim. The thing is, you have to get the vicitm to show those marks. A bystander could report it, and someone may follow up. I have been in a situation similar but it never got taken this far.
