News organizations are in the business of grabbing and keeping adult viewers.
In this day and age that means they've allowed coverage to get pretty gritty. As adults, we can choose to allow these experiences into our world - subjecting ourselves to the graphic details of the gruesome or hideous aberrations of a few sick humans. In their inexperience, kids have not yet developed rationalizations to help buffer their fragile emotions to the horror laid bare in these news images. The reality of today's media strategies makes it inevitable that news networks will certainly continue to broadcast outrageously shocking material. YOU are the barrier and the protector for your child.
