Philomena Cunk:  _ One _ in 20 people has been a victim of crime . Which means that 19 out of 20 people are criminals . No wonder we need police . In the olden days , if someone did something wrong , there was nothing you could do except form a mob with your neighbours and hunt them down and kill them . But today , we 've got one other option , thanks to Sir Robert Peel who in 1829 discovered the police here on a spot marked today by a ceremonial wind turbine .
