A friend of mine was in a very minor traffic accident. Nobody appeared to be injured, so police were not called. About six months later, my friend was sued for nearly a half million dollars and lost. His wages were attached for years.
His lawyer told him that if he had made a police report, chances are the suit would not have been successful.
My poor friend had to get a second job at a tire shop in order to make ends meet for his family. One day, the guy who sued him came into the tire shop and saw him working there. He went back to court and got part of that wage too.
