After John Knox is arrested he is seen wearing a D,O,C, (Dept of Corrections) jumpsuit. It is shown to be week 7.
D.O.C. would mean State prison. Knox never could have gotten through a trial, conviction and sentencing in that short period. He would have been held in jail, not prison, until trial.
When going through the security footage, Knox types "search database" to find his son arriving, then types "delete time stamp" to erase that part of the footage. That is simply not possible.
Character has an MRI scan. The sounds are accurate but the visual is a full body PET scanner.
Miles tells to his father Knox that he signed the papers to sell the family cabin 2 years prior.
Knox should have moved the hidden gems in another location before doing that, since he was still healthy.
