[="Springcat"]How can it be that no one gets arrested[/quote]

Whatever gave you that idea? Just off the top of my head I can think of at least one person in the past couple of months that's been sent to court regarding burglaries: he admitted to around 30 or so burglaries and attempted burglaries in the Forest Hil/Crofton Park/Brockley area...

What are you talking about? When and where do the police do this? The only thing I can imagine being the case is constables briefly making people aware of the Occupiers Liability Act 1984.
