Crime stoppers?

Another interesting anti-crime initiative, this one courtesy of Northamptonshire Police who are apparently about to spend their summer nights bellowing at residents who've left windows open.

Should this one spread I fear it may cause more crime, anyone - police or otherwise - waking me in the middle of the night might have cause to regret it. I'm sure it will give the 'officers' some amusement as they pursue their lonely night patrols.
