Early in my career, I made a mistake on a report and denied a client their claim on the grounds that the car accident appeared to be a result of their negligence as opposed to the negligence of the other party. I found out later that I was too quick to make that decision. I had not spoken to the police first, who later informed me that the evidence I was looking at was taken after the vehicles had been moved from the scene. They showed me photographs of the vehicle immediately after it had happened, which clearly showed the other party was at fault. I was too quick on the draw, and I learned that every case requires due diligence.
