The plain language of your post only indicates that the reason he was “protected” was because the independantly developed military intelligence could not be shared with the FBI. Lawyers told intel folks “you can’t touch him” in that context. Again, based on what you posted.

I give up. You are obviously correct. I must completely forget all the years I worked at NSA.
