More clear-cut cases are of less interest. And again, perhaps the fact the media is selling eyeballs is to blame. With "controversial" trials - like the O.J. trial - people like to watch and argue about whether the defendant is innocent or not. It is like watching your favorite soap opera. They just want to keep you watching.
Crimes that make you throw up, however, don't keep you watching. Boring or routine crimes - or the millions of unsolved crimes - they are not "newsworthy" as there is no "hook" to keep people watching through the commercials.
So, if you plan on being the victim of a crime, make sure you are appealing to the viewer demographic, and have a nice, clean murder without a lot of gore that turns off advertisers. And be sure the crime is controversial or the facts are murky. Otherwise, no one will give a shit, quite frankly.
