It's quite funny to say so, especially I've seen a (BBC, I think) news/document about exactly such things happening. Unless of course it was all fake, and they all were actors or it wasnt in Luton...
The daily mail article talks about two people who were arrested and charged for attempting to do this. Hardly evidence of a no go zone for police -- quite the opposite. You're repeating nonsense that's been widely debunked and not providing any sources.
