Randall Dale Adams, who once was three days from execution for the slaying of a police officer, was freed Tuesday under a court ruling that he didn't get a fair trial.

Adams, whose conviction was questioned in the critically acclaimed documentary film "The Thin Blue Line," said he was happy that two courts ruled in his favor but won't feel vindicated unless his name is cleared in a second trial.

Adams had been ordered released on a $50,000 personal recognizance bond set Monday by state District Judge Larry Baraka. But prosecutors tried to get Baraka removed from the case, saying he was biased in Adams' favor.
