“I don’t see anything in our work that our agents should have done differently,” Comey said, adding that the FBI has the thankless job of looking for needles in a haystack, while figuring out “what pieces of hay might become needles.”
The idea of a “watchlist” could be useful for flagging terrorism suspects who go out and buy, or try to buy, arsenals of weapons? Isn’t that the kind of thing they might want to remain aware of?
