Just out of curiosity, how on earth would the NHS run background checks on these foreign doctors? They are totally unqualified to do a check that could possibly catch someone like the doctors recently arrested.
The only possible way to prevent something like this happening again would be—not to hire Muslim doctors. Or for the intelligence agencies to pick up on them by monitoring all their phone calls and meetings, etc.
But the more Muslims you have running around, the harder that will be to do. There’s just not enough manpower to watch them all, especially since they are instructed not to profile or to be seen watching them.
Drain the swamp.
