My point was that to have another couple of bobbies plodding up and down London road and the threat of long term prison will not deter people who are intent on it from breaking into your house.
Keeping your local area clean and tidy, well lit and getting to know your neighbours so that they are aware of who lives in your house is a far better way of preventing burglary.
Preventing the kind of people who would be intent on breaking into your house from existing in society is a bigger challenge - again not solved by putting half the population in prison.. however to witness a society like this, catch a flight across the pond. This should prove that it simply does not work.
