Nobody knows why a family’s two pit bulls blasted through the back door, mauled an infant girl to death and chewed up her grandmother, who tried to get her to safety. The grandmother, who survived the attack, had been baby-sitting at the time, she told Las Vegas Police. It appears that the dogs burst through a screen door of the North Las Vegas house and began attacking the 4-month-old, who was sitting in a stroller, police said.  “They just went right for the little girl,” North Las Vegas police Chief Joseph Forti told The Las Vegas Review-Journal. Grandma said she tried to “take the girl into another room, but the dogs forced their way in before she could close the door.” When police arrived, the dogs were still acting viciously, they said. Police shot and killed the pit bulls.

Oprah stays political. In recent weeks, rumors have surfaced that there’s an Oprah rebellion afoot. Word is that Oprah Winfrey’s announcement that she would not be allowing Alaska Gov. Sarah Palin to appear on her show, has sparked a backlash from women who say the Barack Obama supporter should provide equal time. But an impending insurrection doesn’t seem to be causing the talk-show diva to be less political. Today, Oprah will dedicate her show to a Senate bill targeting child predators, according to a release issued Friday by Chicago-based Harpo Productions. “What you are going to see is going to shock you to the core, but I’m asking you to please not turn away because this is happening in our country, to our children, in the United States every day,” said Winfrey, who says that show will highlight the “extent and pervasiveness of child pornography trafficking in America.”  The release says that Winfrey will ask viewers to contact their senators about U.S. Senate Bill 1738, the Protect Our Children Act. The top is nothing new for Winfrey, herself a victim of child abuse. In 1991, she testified before the U.S. Senate Judiciary Committee in support of a national database of convicted child abusers. The hearing led to the signing of the so-called “Oprah Bill” in 1993. Her “Oprah’s Child Predator Watch List” has resulted in the capture of nine child predators, according to Harpo.
