“passengers are asked not to congregate near the planes' toilets“

TSA spokesperson: "We frequently say security is not a spectator sport... we can't be successful about stopping terrorism without everyone playing a role“

The point he misses is that the role of the passengers shouldn't be to prevent terrorism.  The plane itself should handle that.  If having passengers “congregate” near toilets is a real threat, then the plane has much more serious security problems that need to be dealt with.  Where did they find these people who come up with this nonsense?  TSA == Totally Senile Administration?
