We all know that there are obvious practical issues with removing people when they are here, which is why I said it's better that we don't let them in in the first place. Much more could be done on that side of things.
Err, turning them back at the point of entry
IS what immigration control does - you don't need to see much by the way of documentaries, news reports, and articles in technical journals to realise that they do a
lot in this respect* But, this whole thread is about dealing with people whop are
already here - so discussions about turning them back on entry are moot. * At Dover for instance, they have whole-vehicle X-ray equipment, cameras looking at the underside of trucks, sniffers that can detect the extra CO2 from people hiding in boxes or containers, etc, etc. It's a far cry from some solitary guy, counting down his days to retirement, casually taking a peek in the back of a few lorries.
