Ummmm -
I agree that JTP initially spoke about the murder rate. However, his question quickly turned to the matter of the fear of crime in general. It was to that matter that my initial answer was aimed at.
I would also add that in my experience (as a former police officer), more and more people are increasingly unwilling to report 'minor' crimes because they simply believe that nothing will be done about it. And to a large degree they're right and I suspect that given the reduction in police officers since 2007 (when I quit) the situation has only got worse. When I was a uniformed officer, it was not uncommon to be called to job where the victim had initially phoned the police and upon arrival to be told that they didn't want to pursue the matter any further because either, a) they couldn't be bothered to make a statement; or b) they didn't think that the police would pursue the matter in any meaningful way.
In general and taking my own personal experience into account, I believe that the levels of crime in this country are significantly higher than the official figures would have you believe.
Also, I believe that burglary (when the house is unoccupied) is now classified as a 'minor' crime... but that's another matter.
