If our Border Force and Police budgets and staffing levels have been cut to the extent that they can barely control illegal immigration, or keep track of potentially radicalised UK nationals returning from places like Syria at the moment, then how are they going to be able to cope with the massive increase in checks required as a result of hard border controls from Europe?
It'd be ironic if the levels of illegal immigration and risk of terrorism actually increase as a result of the decision to leave Europe.
-edit- I did a job at an airport a couple of weeks ago and had to go through security, with a bag full of tools, which took ages. (If I'd known the job was airside I'd have only taken the essentials)
Anyhoo, at the moment everybody
has to be checked on the way out, that won't change, but we only need to check international travellers from outside the EU on the way back.
On the way back out from the job I ended up in a queue that I hadn't been in for years, it was the immigration control queue for international visitors, and that took a while to get through as well.
So it could take as long to get back off a plane as it currently takes to get on a plane at our airports, even if they can pay for enough staff to conduct the checks...and that's only airports.
Fuck knows how long it'll take to check a ferry load of passengers, cars and lorries on the way back in, when we already have queues up to 30 miles long on the way out.
There probably isn't even enough space inside the terminals to hold that amount of traffic, so they'll either have to just waive them through (unchecked), or keep the ferries circling at sea until they have the space to offload them.
