Humans killing humans for various reasons... namely, bullying... and the most common against those they think can't fight back, or seek help. Then they cover up their sins by putting on the wide-eyed innocent look, and one wonders why some kids have meltdowns in the presence of bullies who have changed their spots.
I had some scary babysitters, and some of them thought I had the devil in me. All my life people have accused me of being "evil", even if I hadn't done anything. Other than being wierd in their eyes... and when I'd had enough and got angry, I was a child with rage problems. "Gee, I don't know why she's upset, something must be wrong with her."
The same thing happened to my kids. People trying to hurt them, the schools being biased, my daughter got beat up by someone twice her size every day in elementary school right in front of the playground attendants, until I told her to hit back. So, she punched the bully, knocked her down, and then the bully left her alone after that. Then she got into trouble for hitting. I told them if they weren't going to intervene, she was going to take the matter into her own hands.
There was a local news item of an autistic child being bullied by kids and the school officials didn't do anything about it. So, one day the boy had enough, and threw a fit. He got handcuffed and they called the sheriff. His parents took him out of the school, they were furious at his treatent. He looked happy and relieved to be out of there. I can relate to that completely.
I'd post the link, but I'm not sure if I can yet, being a newbie to this site.
