dunno, depends on the 'crime'
I am usually very pro-revenge attacks, but seeing as I am a skinny bloke I would always go for the smashing them on the back of the head with a brick approach.
I don't want to give them a chance to hit me back.
I hope Frankel wins, especially now I have told everyone who i get the train with that it will win. Otherwise I might get thrown off a high speed train out of Waterloo tongiht.
