An Australian man who posted a disturbing video of a man swinging a baby wildly by the arm says he was arrested for downloading abusive material. In an effort to find the baby-swinger, London police traced the video's IP address back to Australia, where federal police raided a man's home, seized his computers, and charged him with accessing, downloading, and uploading child abuse material with the intent to distribute. The man warned other uploaders to "be very careful of what they post when it comes to children." There are no reports that police have tracked down the individual actually swinging the baby. [MSNBC]
