Nancy Grace: Avery is Guilty ... But Netflix is Awesome

Nancy Grace has made it clear ... she thinks Steven Avery is guilty as sin, but she thinks "Making a Murderer" -- an advocacy documentary which makes him look innocent -- is a great thing for the criminal justice system.

We got Nancy Friday arriving at LAX, and she made it very clear ... all the hubbub is misdirected. But she's not ruling out the chance Avery can once again walk out of prison a free man.

One thing's undeniable ... her flying getup looks comfy.
