Taking pics of kids being bad?

It annoys me to no end when parents put pics on facebook of their children misbehaving. A recent video was of a 2 yr old throwing a tantrum and kicking her older sister in the face. The mother laughed the whole time then claimed to 'whoop her ***' afterwards. Even the lesser things like scribbling on the walls or climbing on furniture turn up in pictures everywhere. How can you teach a child right from wrong if you are always laughing with a camera in your hand? doesn't that send the wrong message to young children?
