Maggie recognizes Frank Cutler and watches the video of her and her deceased husband Jason with Frank looking right at them. OA states there is no scar on his neck, well, in the surveillance footage where Frank bought the drone, they were looking at the right side of his neck. In Maggie's video they are looking at the left side of his neck, obviously there would not be a scar. No Special Agent would gaffe this that grossly.
