Which one? The one that died from the boy friend and the ex-girlfriend? AP got a lot of sympathy for that one for a while. Until it turned out he was pretty much a sperm donor for the kid and took off.
Or the one he supposedly beat last year? Those allegations weren't public (to my knowledge) until after the incident with the 4 year old and the switch came to light last week. Hard to be outraged over an incident you don't know about.
But as we have seen time and time again it is quite easy to become outraged or at least feign outrage over something we know next to nothing about.
