  He did not wait to see what state Mr Coxon, who never regained consciousness, was in, the court heard.
  Judge Keith Cutler said: "What clearly should have been a weekend of fun and enjoyment turned into this tragedy."
  Mr Coxon's brother Jonathan said after the case: "We can see very few circumstances where there would be sufficient provocation to justify this kind of cowardly attack."
summary: A man has been jailed for four years for killing a fellow scooter enthusiast who urinated on his leg at a rally.
