This type of event has no boundaries or selective national discrimination. The few create an environment for the many, especially in this context. Cross border intelligence sharing, whether the UK is in the EU or not, is highly important.

A Pakistani with a UK passport can easily travel to Hamburg/Cologne/Munich etc and rent a car to mow dow revellers at a beer festival or Christmas fair.
Co-operation and intelligence sharing, in the context of our current environment, has to be at the forefront of European and indeed global counter terrorism operations.
