You should always call the police however I don't think it'll matter much in this case...it sounds cut and dry. Call up his insurance company and start a claim. Can you post any pics of the damage??
...and yes you're right, once that absorber gets cracked technically it needs to be replaced.
I'd call as soon as you can man...there's no real point or benefit in waiting. Get that town name as soon as you can and get his insurance a call.
