When it doesn't it hits the fan, when it works its drinks all around in the pub.
Seen this all before in other operations.
The problem is that your actual terrorist bomber is small fry equiv of a bagman.
What all security forces want is the mister big, the planner, the bomb maker the higher level who don't take part in actual operations.
So my monitoring the small fry you hope it will lead to the top echelon.
If it works pints all around.
If it doesn't !!!.
Old Blighty is a hotbed of rampant Political Correctness and Affirmative Action of which the wildest-eyed American Leftists can only dream. The British Loony Left has been bending over backwards to fondly osculate the perineal regions of assorted Third World Clymers for decades. The Left has all but crippled the police, to make British cities less safe for the law-abiding than Al Capone's Chicago.
This is the natural result of inviting in, feeding and educating Muslims in our world. Free food, medical care, and welfare payments have given these young terrorists the time to spend at the feet of radical imams in their post-puberty years, and before they are married of to a cousin or two. Yes, many Muslims are now very hard-working and are fully economically integrated. But to what purpose? To support Jihad?
The only question is: Has Islam been "high-jacked," or is Islam just The Church of The High-Jackers? I see no sign that the "Moderates" are cracking down on the "Extremists." Much to the contrary, they provide a support structure for them!
I hope someone in British Government is surreptitiously thinking of landing giant new Airbus after Airbus on some alkali flat in the Sudan and discharging Muslim deportees. That's what might buy us some peace ... not appeasement of these well-fed vipers.
