You can’t so why suggest it?
“You can’t so why suggest it?”
Not everything is provable; that does not mean that we do not act on beliefs about reality that we cannot prove, or that we should not tell others of our beliefs.
I have talked to several people who are involved in intelligence gathering operations who have told me that the intelligence services have stopped numerous attacks. I know that sting operations have been used to arrest and convict people who tried to contact Islamic radical groups.
I cannot prove that the NSA was involved; they are very close mouthed about such things, for good reasons. But experience and logic imply that they were involved in the intelligence gathering that was used to stop these events.
