So to deter poor people trying to enter a country, one stands idly by while they drown in the sea, or traumatises their young children by sticking them in wire cages with only a foil blanket, away from their mothers?

I agree they cannot be allowed to invade a country in their thousands, and it is a huge problem. But surely proper detention centres, where medical care and humanity are offered is better than getting more and more like Adolf Hitler? What next? Gas chambers? Gunning them down as they arrive?
