You are clearly forgetting about Interpol, the international organisation with far wider membership than Europol, which has been going a lot longer than the EU - and of which we are still a member. And no, I'm not suggesting we don't do a deal. It has been made clear that we want a deal; the EU want us to be in Europol too, so unless they do something incredibly stupid, a deal on Europol will be made. It's called negotiation.So what you are suggesting is if the EU and ourselves don't agree on a deal, we will withdraw our security forces.
So if we get wind of a potential terror attack on Paris, we won't do anything?
Just let people die?
And as for deliberately not warning one of our allies - in the EU or out of the EU - of the imminent danger of a terrorist attack - sorry, that's absolute bollocks. If you'll forgive me for saying so (though I'm pretty sure you won't be able to), that is sounding like something that Project Fear wish they'd cooked up.
