I was interested in buying a truck from someone in Kentucky, USA. A friend said he heard the person selling it had performed a hit-and-run about a month earlier. No one was hurt, but police were looking for the perpetrator. Apparently no one got a licence plate number, only a description of the truck. It was pretty obvious the truck had hit something.
Suppose I bought the truck. Would I be responsible for the hit-and-run if they ever found out exactly who did it? I did speak to the police, that I thought I knew who it was, but they didn't care at all.
