“When you really look at the forensic evidence, Steven Avery is guilty of murdering Teresa Halbach,” the legal commentator told ET at the TCA Hallmark Party. “And as a crime victim myself I resent the misbetrayal of the truth, and it makes people mistrust the system. And I don't like what it's doing to our justice system. “

The documentary became so popular that 129,000 people signed an online petition on WeThePeople asking President Obama to pardon Avery. But Grace says it doesn’t give audiences the entire truth.
