Possible terror attack Manchester

[fazersharp]

If we can supposedly put a number on highly threatening jihadists in the UK, then surely that means we know who and where they are doesn't it?
So why can't we strike first, deporting any non UK born suspects for starters, regardless of their claims that their own homeland is dangerous for them (not our fault), and detain the others under terrorism laws, and see if the threat suddenly subsides.
Meanwhile, when we see dubious looking people at our borders with suspicious amounts of stamps on their passports fling in from known threatening countries, then if they're not born here tell them to fuck right off and bar them for life, and if they are born here then detain them and question them over suspected terrorist activity.
The PC brigade will whinge like mad, but rather them than us having to deal with the aftermath of a bomb blowing up completely innocent people at a pop concert for example. 
We've gotta start somewhere, and it sounds like a reasonable plan to me.

When we finally brexit proper we can be free to do all of that without having the European Court of Justice and  European Court of Human rights overruling all our efforts.
We need our own Guantanamo bay, maybe we could use the Falklands, stopping them at the border is what Trump suggested and he got all kinds of flack for that but it makes sense to say we dont want people coming here who have nothing but bad intentions.

This has been going through my mind, the father of the bomber came here after fleeing Gadafi's Libya we opened our doors to him and gave him refuge, then we helped destroy his enemy and we are repaid by his son murdering people of the very nation that was his savour. So the people who say its because we got rid of Gadfi doesn't make sense, it doesn't fit this story and makes no difference to what happened.

Also corbin saying they shall not win on one hand and then on the other saying he will alter our foreign policy when that is exactly what they want, if he does that then the terrorism will get worse because they will see that the bombing is working. Yes by all means slowly alter our foreign policy but don't announce it and make it an issue and say its to reduce the treat to us.
