No doubt the spotlight makes everything sounds like more than it is, and it is good to have that pointed out, no doubt about that. However, is it really, in itself, proof as such that crime is positively decreasing? Isn't it rather a good support for the idea that it isn't rising, as it may seem because of all the attention to it?
I think you need some sort of change in society for crime to decrease. Maybe better economical circumstances and jobs are in plenty? More and better educated police? Someone invents an easy and safe cure for addictions? A new and better educational system? Or something like that.
I believe a statement like that needs something substantial to back it up.
