People saying they don't mind as they have nothing to hide, most people don't, so why does everyone need to be scrutinised like this? If they believe something is amiss they have the power to check.
This is like saying 'I'm not a murderer, I ahve nothing to kide' so the police can storm your house an take all your electronics etc...
That's extreme example but the point is people, even on benefits, are entitled to privacy. If there's reason to believe something is wrong then they can apply to check.
But everyone shouldn't have to be treated like a criminal because of a few.
It's more and more government sanction intrusion of privacy.
