Citing Mike F's initial post:
Mr. Casas makes a compelling case to keep them around.
All I can say a provocative article and far from realistic. Does he seriously think that the information that may become intelligence exists to undertake such close-in observation? We maybe good at restraining the flow of recruits, we are less good at money and other ingredients in the AQ mix. Yes attacks have been thwarted, others have succeeded.

In the UK I ask what would the UK have been like in July 2005, if the 7/7 bombs had gone off and the bombers escaped? Add in the 21/7 attacks too.

In the USA I am sure readers can imagine an equivalent scene. IIRC the CT adviser, Richard Clarke wrote an article a few years ago on future successful attacks and their impact (lost the link).

No, Mr Casas stay in your "groove".
