On 28th September 2008, Frank McGarahan was viciously attacked, receiving fatal injuries, after intervening when he saw two homeless people being attacked in Norwich city centre. He had been out with friends and relatives and was waiting to go home when the incident occurred. A relative said later: ‘Frank was a fair- minded person. He wouldn't see anyone treated unfairly.’ There have, tragically, been several other incidents of a similar kind in recent years. The case of Jamie Mizen springs to mind – the teenager who was fatally stabbed in the throat with a broken plate for refusing to fight outside the shop where he had gone to buy his first lottery ticket on his 16th birthday. Many of us are profoundly moved to pity and sorrow when we learn of such incidents; frequently we are horrified.
