OK, I would NEVER wish a child seriously injured. Plus, in this case it was too young to know and it is all the fault of the dumb-ass parents. However, I also loath shitty free-range kids in restaurants and, before reading there might be serious injuries, I saw "girl gets head stuck in door" and thought it was hysterical and just what karma ordered.
I really wish something like this, but less serious, would happen to more of the feral brats. Then maybe parents would actually parent.
