Casey says the file shows Sokolov defected in 1985. However, Duckie remembers it as after the fall of the Berlin Wall, which was in 1989.
Jimmy says the time of death was "30 hours ago" and Torres says that would be "about 6:30 last night". That would make it about 12:30am. However, Jimmy's daughter is waiting for help with a school project and they expect Parker to be having dinner with a friend, which would make it early evening.
When Parker is in the interrogation room with the Senator he points out the CCTV camera. The camera should be flashing red to signify it is recording but there is no red light to be seen.
It is not possible to get a usable retinal image from a high resolution photograph, even a 8K UHD photo, if that were possible it would render biometric retinal scanners useless. Retinal scanners that are part of a biometric security system use a low energy infrared beam of light to obtain an image of the blood vessels in the retina, the pattern of blood vessels for a person are as unique as fingerprints. Regular photographs are taken with visible light, it would not be possible to get an image of the retinal blood vessels from a normal photograph. Even if someone took a IR photo of a person they would need to have the camera lens directly in front of the eye to get a usable image.
