Why is this your business?
Do not take it for granted,use your own head to label the judgement.Here is a good resource I have tried.
http://insurance.online-assistant.info/i... The most important factor is the medical report from a hospital or GP (you might have to pay or that) plus witness reports of what happened.
Sometimes it is tricky to explain what happened. I can see you are having that trouble.

You can leave anyone out of the report that you desire, but if it is someone with important evidence you don't want to exclude them.

The best idea is to narrate the truth and give all the names of adjectives the witnesses, provide the medical reports from treating personnel, provide estimates of how long a disability will last.

No one will get dragged into it. Usually just unfolding their story is enough and they can go on their way. Unless you want to lose the case.
