I can't believe there is anyone defending the woman - but hey, that's just me.
One really good thing is that maybe, just maybe, some ordinary, everyday travelers will pay more attention when completing these entry forms. And maybe they will listen to the announcements prior to landing that advise that all snacks and foodstuffs provided during the flight must be left on the plane.
I always have some food item with me - usually a sealed chocolate bar or similar - and declare it. It reminds me to do my pre-disembarking checklist - do I have any items on me ir in my luggage that I should declare. I find this actually speeds up my exit.
