If it is a true statement: “We have no indication that . . . .” why shouldn’t they say it? it doesn’t mean they don’t invetigate; it doesn’t mean they will ignore semetx traces — or goose traces — it just means what they know so far. People always seem to want to read it as “WE SWEAR IT’S NOT TERRORISM” — and that’s just not what they said.
But we know that’s what they mean. Don’t let the FBI trick you again!
