The unfortunate thing is, those that vote on laws around this are generally those who have most to fear around abuse of any system set up to regulate it.
They aren’t the blameless who go through their lives just getting on with things, or people who do great things for nothing else than the satisfaction of helping people.
They are in a good number of cases, greedy money grabbing shysters who’d sell their own mothers for the gold in her teeth. And many will have (within living memory) seen unpopular or embarrassing relatives “sent away” to somewhere less embarrassing (the country estate for instance, or Australia). Probably a more significant chunk in the Lords, but still a good number in the lower house.
I can’t see any changes in the law coming up any time soon.
Even Camerons mother has had enough of him. And mothers will forgive most thinks, Except being an immoral, thick, sleezebag.
