It's not enough for me. The places where the dash cam video footage was deleted should be made public. To me, this is a very minor detail.

That said, trained actors will sometimes briefly smile when depicting grief to showcase complex emotions or a stream of consciousness wherein the character recalls an uplifting memory. People might mistake a real person experiencing mental turmoil as behaving "like an actor."

There is also the phenomenon of "duping delight" which is a tendency for people (untrained actors) to smile at unexpected moments while in the process of deceiving others. Again, people could mistakenly spot this in a grieving person who has just been given encouragement to speak to the public.

So I can see where people are coming from with this idea, but for me it is insufficient. Since I don't know what really happened, making a big deal out of something that is (in my mind) such a minor issue is needlessly cruel if it is the case that the kids were actually murdered.
