That's basically all your personal biases on display. Chomsky is certainly not news. Nor do I expect them to cover absolutely everything. Like I said, I use multiple sources but even still my head can only hold so much and CNN only has a finite number of reporters. Like I also said they certainly have editorial bias because they have to choose what to cover given finite resources. The fact they miss some of these tiny stories is expected. That doesn't make them unethical or inaccurate.
