I cannot criticize your post. You and I do not know the circumstances this photo captures.
The caption stands.
If I were there, I would never call someone trying to get food, water, shelter, toilet paper, diapers, medicine, etc... a looter. Somebody taking watches or TVs, they are looting.
And I agree, the caption stands, because that is what the reporter put there, regardless to the reason or situation, and I certainly don't fault you in any way, shape, or form for that fact.
