Its rough out there in the streets

Been there several times. Unfortunately you are better off just forgetting about any sort of justice and moving on. They won't have insurance. They won't show up to court. If you find the person on your own and make contact they will call the police. If they are any type of mental defective or illegal they will have a team of city and state advocates ready to destroy you.

Even if everything goes right and you somehow get them into court they will never pay.
