It has absolutely jack **** to do with terrorism. I'm not going to pretend to be "in the know" about the actual reasoning and nor do I think it's just "cos dey all r racists", there's clearly much more to it than that, but what I *do* know is that it will have absolutely zero impact on the risk of a major terrorist incident. It's like performing brain surgery with a ****ing sledgehammer. The plotting, scheming and organisation that goes into a major incident is not going to be interrupted by "closing the borders and airports". Not even slightly.
