There is 'naf' all to stop these things from going ahead apart from someone deciding they don't want to. If there's no law saying that I don't have to say hello to my neighbour, it doesn't stop me from saying hello?
If we want to share information or use a framework that other countries have in place then do it. If we want to make changes to said framework then do it, that's the pleasure of being out of the control of the EU.
If we share information with EU countries, I'm sure they'll be (depending who you speak to..) grown up enough to speak to us, this is just political bull poo made up by a research company to justify their existence.
