In the chase scene at the school. The chasing car flies over a sand dune then rolls in different directions in three different camera shots.
When Libby is handcuffed to the car and she accidentally rams the Geo that is in front of Travis's car overboard, the Geo has hubcaps as it's going over, but when the camera cuts to the Geo sinking, the hubcaps have been removed.
In the first scene of the halfway house, Libby is pinning up pictures on the bulletin board to her right. The scene later shows her sitting on a bed facing left.
Double jeopardy only applies to crimes tried by the same state or the federal government. If a murder occurred in a different state, it is tried independently of what may have occurred in another state. In practice, if it is discovered that the crime for which a person was convicted did not occur, the conviction would be vacated.
Pay phones in prison do not take coins.
When Libby leaves Colorado for New Orleans, she travels by plane. As a wanted fugitive, air travel would not have been an option open to her as she would have been flagged as wanted and arrested as soon as she tried to fly.
In the Lafayette cemetery, Libby has been put in a mausoleum and then put in a coffin with a body. This is a factual error since burials at the Lafayette cemetery do not involve actually burying people by themselves in a coffin that stays that way forever. The burial process involves putting someone in a very simple wooden box and letting them decompose with other members of family who have been buried before. Also, the process to open a mausoleum is considerably harder than just opening a door. Bricks and mortar, and usually a name plate/stone, must be removed to get into a mausoleum. Also, under the same line there is not a single mausoleum within the cemetery that would have a window in it. Burials also usually involve the traditional Catholic mourning period of 366 days before the mausoleum is opened again, so even if someone had recently been buried, the body that Libby was put next to would not be as "undecomposed" as shown in the movie.
Libby is shown as being pardoned at the end. As is often erroneously shown in films about the wrongfully accused, anyone committing a felony, such as possessing a firearm, while being a convicted felon, would still be subject to being prosecuted and imprisoned.
When Libby enters the BMW dealership and asks the salesman to run a credit check on Angela Greene, the salesman returns and provides her with a current address. However, in the next scene, when Libby attempts to find Angela in Colorado, a neighbor informs Libby that Angela died three years earlier. Therefore, there would have been no available credit report and current address for a person who had been dead for three years.
(When someone dies, their credit report is not deleted right away.)

During the trial, the prosecutor shows the knife used to kill Nick. The blood is bright red when it should have been dried by then.
As Libby is getting ready to meet Nick to get Matty, she opens the cylinder of the pistol she took from Travis. The closeup of the cylinder shows a round with the firing primer dimpled, indicating it already has been fired.
When Abby is on the phone in prison she is wearing her wedding ring. All jewelry would have been confiscated when she was first arrested.
As the blue Chevrolet rolls, the cable used to pull it over can be seen.
When Libby phones Angela in San Francisco (from in prison), you can see the top of the Hotel Vancouver (in British Columbia), through the window in Angela's apartment.
The provincial flag of British Columbia is visible beside the American flag where Elizabeth is exiting the freeway to supposedly meet Angela and Matty.
The idea that someone would lose his career as a law professor because of a DUI, but secure a job as a probation and parole officer, is ludicrous.
