Kidnapping had never happenned till the Graeme Thorne case in the 1960's I think it was.
Nobody I knew locked their houses and we all left our keys in the ignition in our cars.
Yes there was a rare killing and it was the story of the year.
No one carried knives until Italian immigration and I don't say that as a racist viewpoint since Italian's were by and large a positive and constructive addition to our population.
The population has trebled since I was born but to suggest violent crime has only trebled is nonsense.
