I agree with them, but local "news at 6" shows tend to feel more balanced when I watch them, because they only have about 30 to 60 minutes to report what they need. Only the most important stuff can be reported, due to the inherent restrictions of the medium. Its not perfect. Like you said choosing not to report something is a bias in itself, and local news shows aren't exempt of this. But also, they have an incentive to report stories that their area will find significant, so I prefer it
