Not threatening at all.
Not big enough to hold enough explosives to do any real damage to a structure (they are thin with nothing hidden and clearly an electronic sign).
If someone were trying to bomb the public they'd just drop the bombs in public trash cans and not raise suspicions.
This whole episode is dumb, dumb, dumb.
