"No Man is an Island"

The actress Emma Thompson supports the Refugee Council, and considers the Home Office stupid. (BBC Radio 4, Desert Island Discs, today.)
She is grateful to a judge who overrode a Home Office decision to return a "refugee" to his own country.
The Home Office is not stupid for wanting to return to their own countries people who exploit a (Cold War) Convention concerning political persecution to enable them to circumvent normal immigration controls.
Immigration officials are in an impossible position if controls are out of control. And they are not in control when there is a thriving industry (lawyers, NGOs, etc.) in opposition to them.
This confused and selfish situation is exacerbated by marriage. We are told it is in decline in the UK, but is increasingly used for immigration purposes. It is one thing for women to be able to live abroad through marriage; that is no normative reason for men to be able to occupy other peoples' territory through marriage.
These are not just academic issues. Much unhappiness ensues.
