We already know that the media is not to be trusted when it comes to political coverage, but it should not be reach to consider that they should not be trusted with other things that are "non-political" such as entertainment.
The fact that the media went so hard against Michael Jackson to label him as crazy (though maybe that is true to some extent) while they ignored/covered for so many others makes me think he was innocent of the accusations.
Come to think of it, he was famous as a kid too.

The same reason we do not get many whistleblowers against these people is the same reason we do not get them for politics. They are usually silenced, slandered, or killed for speaking out. Keep in mind the same people covering politics also cover entertainment. And they are all part of the same circles, the news media, entertainment media, and politicians. So it should not surprise you that they silence those who would reveal entertainment media as abusive pedophiles.
