Some time back, there were stories of police breaking in to cars and taking away anything visible, then telling people off for leaving valuables visible where they could be stolen by police. There were C3PO's or whatever they are called locking people's doors while they went out to fetch their bins and walking into unlocked houses to tell people off for leaving doors open and risking letting nutters in uniform into their homes. I think Ambush Predator covered all those and more.
Lately, it seems burglary is in decline. There's no point stealing a DVD player that Tesco sell for £20. There's not much in the average house that has a resale value any more. Burglars are now going for mugging instead so that they get cash and iPhones and don't risk getting the crap beaten out of them by a whole family of enraged people. On the street, they know we are not armed. In our houses, there are many things to hit them with.
So, since the burglars refuse to do their jobs and are effectively on strike, the Police have been drafted in to help.
How long before the first householder is in court for battering a policeman who broke into his home in the middle of the night? If they can no longer get you for battering the burglars, they are sure to get you for battering the Burgle Squad.
It'll boost the arrest figures, but it won't achieve anything else.
