So. We DO NOT KNOW where the attackers in cologne were from - they may have been recent immigrants, they may have been German, Belgian, French, British for all that we know.
But, you know - it is the fault of immigrants.
We DO NOT take part in Schengen - therefore if those responsible want to travel here then our own border controls (which we have because we are not in Schengen) are in place, and would only allow people with passports to get here unless under a recognised refugee process (which has additional controls).
But, you know these big gangs of migrants are coming here to do the same thing.
These attacks happened in different European countries with different policing approaches and priorities. Local politicians have also been accused of orchestrating the cover up (and you know it was a cover up).
But, you know the same thing will happen here because nobody is watching for it.
Basically, a bollocks argument - there is no link between what happened in Cologne and being in the EU. It is bullshit. Even Farage (who initially made the claims) is trying to backtrack from it because he realises it is rubbish.
Also, I am sure his incredibly patronising and at times openly chauvinistic approach has endeared him to many, many people last night.
