Here's the latest crime news from the Guardian:
There has been a surprise 8% drop in crime across England and Wales, according to official figures, suggesting the long-term decline in crime since the mid-1990s has resumed.
As near as I can tell, crime declines are always a surprise to the folks who look for answers solely in social trends. But Britain's continuing decline isn't a surprise to everyone. Europe adopted unleaded gasoline in the mid-80s, and EU countries all showed drops in lead emissions in subsequent years. In Britain, lead emissions began to decline about a decade later than the United States, but they made up some of that gap via a much steeper drop. So, to the extent that the crime decline is a function of less lead exposure among children, they're about five years or so behind us. This means they probably still have a few years of crime decline ahead of them.
