How does a 4-year-old have a fully developed sense of self?

Here's what I saw on the video. I saw a white woman put a child into the back of a pretty nice SUV and proceed to beat the snot out of her. I don't know she's Irish, I don't know she's a Traveller, and quite frankly I COULD NOT CARE LESS.

Child abuse is still a crime in the US, as far as I know. If my brother beat his kid, and I knew about it, and I actively tried to hide him - I'd be arrested too. (although, personally, if I knew my brother committed a crime, I'd turn his ass in. And he'd be disappointed in me if I didn't.) That's just how the system works.

If it can be proven without a doubt that she's being picked on because she's a Traveller, fine, go for it. But right now she's being picked on because she beat up on someone less than half her size.
