Here is the link http://news.bbc.co.uk/1/hi/england/lancashire/7636040.stm The copper's daughter had an arm broken and his son was glassed. The copper attends Alcoholics Anonymous. He took the law into his own hands and dished out a hiding. The guy who glassed his son got a community sentence and the copper got time. Both sides are wrong in law but look at the disparity of sentence.
