Why Does No One Cares To Protect Them?

How do you feel watching this video? The U.N men walking around with huge guns but never care to go to camps and other areas where they are needed to protect these defenseless women and children, why? Why does this young girl have to be in the streets getting raped? This is outrageous! If the U.N.is not there to protect the people, who/what are they protecting? Why are they there?
