Who Will Protect Our Children?

There are somethings in life that I do not understand. One of those things is how an anyone, anyone can abuse children. I have a really, really hard time understanding the mind set of someone who could look at an innocent face and harm him/her. The story here about Judith Leekin is truly outrageous. Wasn't there anyone who saw, heard or noticed something wrong? Was there anything that came across as strange to Children Services about this woman? Wasn't there anyone that could have saved these children?
