No one has made any claims about mass expulsions except you, springing.
You suggested that the EU would expel all EU migrants if there was a Brexit. Expelling a specific group of your popuation is 'a mass expulsion'
You have still not given me an example of these mass expulsions that your fear Britainis about to repeat..
no system for checking everyone who comes in - just checks against watch lists nor checking that people leave. The Home Office has resisted collating that data because it would probably highlight the scale of the migration problem
You are conflating immigration and border controls here - not all arrivals in the Uk are immigrants; most are tourists or business visitors.
I'm not conflating anything. I was told that we control our borders because we have passport control. That is very disingenuous as we all now that controlling borders is much more than that - it's deciding who comes here to visit, for how long, who comes here to live etc. Controlling borders is not flashing your passport at Heathrow.
Controlling EU arrivals in the way you suggest would require visas for all visitors, which would be hugely disruptive for business and tourism.
I'm not limiting it to EU arrivals, Everyone should be 'controlled' on entry 9and exit). That should be part of our basic security precautions - knowing who is in our country and who has left. Most of the rest of the wolrd operates that system. It prevents terrorists from swanning across 11 European borders on their way from ISI HQ to western Europe.
Dominic Raab has suggested that visas for EU citizens are on the agenda and indeed it's hard to see how border security can be greatly improved without some system of checks before travel.
Lol. There are already systems that check before travel when you arrive at airports you cannot just pitch up and sit on a UK bound plane because if that airline carries you illegally it will be fined. It would be quite easy to link an electronic visa system to an effective border system (something we do not currently have) - IF visas are needed which is complete fantasy anyway.
Obviously this isn't good news for EU migrants and suggests that we may have more cause for concern than we previously thought. It's useful to have confirmation of Leave camp thinking on this point I suppose
The 'LEAVE camp' wants a UK that controls its borders, can decide who to invite from throughout the world to come and live in the Uk and share their skills with us, and the ability to deport foreign criminals.
If tat inconveniences the world - tough. It's worth it to inconvenience terrorists.
