My story really hasn't changed. I guess im just not describing things clear maybe? Or didn't describe it clear in the original post. Either way I wasn't the only person there. Both the police and insurance company had my buddy fill out reports. We were literally 10 feet from each other when it happened. Everything he said matched my version of the events no matter what way you look at it.
By changing I mean your adding more detail which is common over time....but if two eyewitnesses fill out reports and they are identical it is very rare and usually infers that the two eyewitnesses have spoken about the event. I have questioned eyewitnesses at trial and many times they seem to have seen different events.
