Firstly this is on the BBC website so I'm guessing this must true/truish?
It says
*Police enter homes as break-in warning

South Yorkshire Police have adopted an unusual tactic to help warn people about the risks of burglary - by breaking in to homes themselves.
Officers attempt to enter unlocked houses, and leave a balloon to alert the residents about the ease of their entrance.
Joe Inwood reports.*
This can't be right can it? Does this mean the police can now enter your home without a warrant if they can get in somehow?
