Yep, as far as I am concerned they give up their human rights as soon as they break the law. Get caught inside my property without permission and your evening is going to end very badly, may even involve a chalk outline.
As for what the law thinks? The police in this country are controlled by a socialist government, and the government has this idea that they can protect you, even though 999 is a government sponsored dial a prayer. They are not going to be there when crack head toerag enters your property with bad intentions, and previously mentioned toerag is not going to stadn their patiently while you call the police and wait for them to arrive.
I am not advocating taking the law into your own hands, but you have got to protect yourself and your family, and face the repercussions that the law decide afterwards.
There is an old saying, better to be judged by 12 than carried by 6.
