Everyone is entitled to there opinion, I just don't like it when people jump to conclusions. In this case the mother has tried counseling, therapy, and other avenues and has been turned down for every one. In some instances, she was told in front of her daughter that everything is fine.
The idea that these two should be charged with a crime is ludicrous. Her mother was always too leniant. Citing her own short falls as the reason. Now she is scared for her daughter's well being and locking her in a room is horrible? I think it is worse if she ran off, got drugged up, and had REAL bad things happen.
I certainly don't agree with the statement that if a kid runs away there is something wrong in the home. Not all kids are easy to deal with, or act perfectly. Sometimes you have to protect them from themselves.
I don't want to be misunderstood either, I am not saying her mom is a perfect parent. All I know is that you should walk a mile in her shoes before you think you have any idea what is going on.
