"The media isn't saying he did it, because they would open themselves up to lawsuits."
The media isn't saying he did it because it is their role to provide you with information with which you make your own conclusions. They should not provide you with conclusions. In particular, people tend to view trying people (even OJ Simpson) in the media as an abrogation of journalistic integrity.
Journalists are not commentators or analysts. Rush Limbaugh is not a journalist, he is a commentator and entertainer. Too many people prefer Rush Limbaughs to tell them what to think to journalists who provide objective information.
