I fear that there still continues to be people whose ideology prevents them from taking precautions and thinking clearly
What on earth are you trying to say here?
Well, Birdybirdy, what I am saying is that despite the existence of Europol, serious criminals from EU countries are walking into ours. We are not being informed until after a dreadful event such as this.
The ideology I refer to is the EU ideology, which promotes the belief that being a borderless group of 28 nations is a good thing, and the fact that criminals can come & go as they please is just something we have to put up with.
And because insufficient checks on those arriving from any EU country are not performed, or rather names do not appear to be flagged up on the computers at Passport Control in a timely fashion, I would suggest that it would be prudent of us to practice a bit of circumspection.
And that's from a Detective Sergeant.
